ALL COUNTRIES

1.Combinatorics, Geometry, and Physics
 Dates 02 Jun 2014 → 31 Jul 2014
[ID=616764] Go to top of page
 LocationErwin Schrödinger Institute, Vienna, Austria
 Abstract The goal of this thematic program is to bring together researchers in mathematics, computer science and theoretical physics in order to make significant progress on the outstanding problems at the interface of combinatorics, geometry and physics. The first point of focus of this program concerns statistical physics on graphs drawn on two-dimensional surfaces. This will be studied in three stages: on a fixed graph, on a random graph, and finally through the study of the interplay between the last two situations as exemplified by the paradigmatic KPZ relation.

2.MNM@CASON'14 — Multiplex network Mining - Special session @ CASON'14
 Dates 30 Jul 2014 → 01 Aug 2014
[ID=617799] Go to top of page
 LocationPorto, Portugal
 Abstract Complex networks used to model interactions in real-world phenomena are often heterogeneous network with different types of nodes and edges. Focusing on a single type of nodes, a complex network would be better described by a multiplex: a set of nodes related to each other with different types of relations. This representation is much richer than simple complex networks often used to model complex interaction systems. However, this poses the challenge to provide adequate answers to all basic network analysis tasks that have been studied and provided in the recent few years for the case of homogeneous networks. This include for instance: the problem of node ranking (computing nodes centralities), community detection, link prediction, information diffusion models and network visualization. Almost all work in the field of multiplex network analysis are based on transforming the problem, in a way or another to the classical case of homogeneous network analysis. Existing approaches include: layer aggregation based approaches or applying ensemble methods on results obtained on each layer aside. Little work has focused on analysing all layers at once. The goal of this session is make the point on new approaches for multiplex network mining.
 Topics Models and measures for multiplex networks. - Co-evolution of layers in multiplex networks. - Layer aggregation approaches. - Vertex similarity in multiplex network - Community detection in multiplex network - Link prediction in multiplex network - Multiplex network evolution models - Multiplex network and dynamic network mining - Ensemble learning for multiplex network mining - Applications of multiplex network mining and modeling.

7.Integrability and Cluster Algebras: Geometry and Combinatorics
 Dates 25 Aug 2014 → 29 Aug 2014
[ID=575473] Go to top of page
 LocationProvidence, United States
 Abstract This workshop focuses on certain kinds of discrete dynamical systems that are integrable and have interpretations in terms of cluster algebras. Some such systems, like the pentagram map and the octahedral recurrence, are motivated by concrete algebraic constructions (taking determinants) or geometric constructions based on specific configurations of points and lines in the projective plane. The systems of interest in this workshop have connections to Poisson and symplectic geometry, classical integrable PDE such as the KdV and Boussinesq equations and also to cluster algebras. The aim of the workshop is to explore geometric, algebraic, and computational facets of these systems, with a view towards uncovering new phenomena and unifying the work to date.

[ID=553503] Go to top of page
 LocationInstitute for Mathematical Sciences, National Univ, Singapore
 Abstract Applications of moments of measures in polynomial optimization led to a number of breakthroughs in optimization and real algebraic geometry, as well as to better understanding of ways to encode measures. Other similar threads are recently seen in the theory of integration on polytopes and counting of integer points in polytopes, as well as in quantum computing. The aim of the program is to futher investigate relations between these topics and inverse moment problems, i.e., questions of reconstructing measures from a set of its moments, which are traditionally attacked by purely analytic tools. Activities will include two 4-5 day research conferences, one quantum computing workshop, and one graduate student winter school/workshops.

26.ICERM Semester Program: Phase Transitions and Emergent Properties
 Dates 02 Feb 2015 → 08 May 2015
[ID=592142] Go to top of page
 LocationProvidence, United States
 Abstract Emergent phenomena are properties of a system of many components which are only evident or even meaningful for the collection as a whole. A typical example is a system of many molecules, whose bulk properties may change from those of a fluid to those of a solid in response to changes in temperature or pressure. The basic mathematical tool for understanding emergent phenomena is the variational principle, most often employed via entropy maximization. The difficulty of analyzing emergent phenomena, however, makes empirical work essential; computations generate conjectures and their results are often our best judge of the truth.

The semester will include three workshops that will concentrate on di fferent aspects of current interest, including unusual settings such as complex networks and quasicrystals, the onset of emergence as small systems grow, and the emergence of structure and shape as limits in probabilistic models. The workshops will (necessarily) bring in researchers in combinatorics and probability as well as statistical physics and related areas. We aim to have experimental contributors for workshops 1 and 2 where we will highlight the comparison between computational and theoretical modeling and the real world. This will be combined with computational modules for the student participants.

27.ICERM Workshop: Crystals, Quasicrystals and Random Networks
 Dates 09 Feb 2015 → 13 Feb 2015
[ID=592207] Go to top of page
 LocationProvidence, United States
 Abstract The prototypical emergent phenomena are the bulk 'phases' of large collections of molecules, such as the fluid and solid phases. The solid phase is understood to emerge from an energy minimizing ideal crystal by the addition of random defects as energy increases from its minimum, the crucial/amazing fact being that the phase preserves something from the ideal crystal that unambiguously distinguishes it from the fluid phase. In this workshop we will focus on two significant variants of this classic picture: quasicrystals, and complex networks/random graphs. The analogue of energy minimizing crystals for quasicrystals are aperiodic tilings, such as the kite and dart tilings of Penrose, and for complex networks the analogue of energy minimizing crystals are (multi-partite) extremal graphs, graphs which minimize the number of subgraphs of some type. The workshop will focus on extremal graphs and aperiodic tilings and on the 'solid' phases they are believed to yield when random defects are introduced. It is hoped that progress can be made by pooling the expertise of researchers interested in the various aspects of these subjects.

29.ICERM Workshop: Small Clusters, Polymer Vesicles and Unusual Minima
 Dates 16 Mar 2015 → 20 Mar 2015
[ID=592184] Go to top of page
 LocationProvidence, United States
 Abstract This workshop will explore emergent phenomena in the context of small clusters, supramolecular self-assembly and the shape of self-assembled structures such as polymer vesicles. The emphasis will be on surprises which arise when common conditions are not satisfied, for instance when the number of components is small, or they are highly non-spherical, or there are several types of components. Interactions vary from hard sphere repulsion to competition between coarse-grained liquid-crystalline ordering competing with shape deformation. Examples of this behavior are common in materials such as bulk homopolymers (rubber), copolymers, liquid crystals and colloidal aggregates. A basic mathematical setting would be to consider small clusters of hard spheres with isotropic short-range attractions and study the shape of the clusters as a function of the number of components. One known surprise is that highly symmetric structures are suppressed by rotational entropy. This emphasizes the need to accurately count the number of particle configurations that lead to the same final state. Small clusters can also generate anisotropic building blocks which can in turn serve as nano- or meso-scale building blocks for supermolecules and bulk materials (supramolecular chemistry) freed from the limited scope of atoms and quantum-mechanical bonding. These structures frequently possess topological defects in their ground states because they lower the energy. The challenge is to determine the shape and equilibrium defect structure of such superatoms and the number and geometry of their arrangement. The number of defects determines the effective valence of the super atoms and the global geometry of their arrangement determines the types of directional bonding possible when defects are linked together. The phenomenon of the appearance of singularities/defects because they are minimizers not necessarily required by topology or boundary conditions is also encountered in the study of harmonic maps. Moving up to self-assembly of large numbers of units, block copolymers self-assemble into a wide variety of structures including vesicles, nano-fibers and tori. Many of the structures formed are essentially two-dimensional surfaces embedded in R3. The mathematical challenge is to find both the shape and the order of the assembled object. This requires minimizing of a functional that depends on both the local and global order of the relevant matter fields and the shape of the surface.

30.ICERM Workshop: Limit Shapes
 Dates 13 Apr 2015 → 17 Apr 2015
[ID=592161] Go to top of page
 LocationProvidence, United States
 Abstract Since the days of Boltzmann, it has been well accepted that natural phenomena, when described using tools of statistical mechanics, are governed by various "laws of large numbers." For practitioners of the field this usually means that certain empirical means converge to constants when the limit of a large system is taken. However, evidence has been amassed that such laws apply also to geometric features of these systems and, in particular, to many naturally-defined shapes. Earlier examples where such convergence could be proved include certain interacting particle systems, invasion percolation models and spin systems in equilibrium statistical mechanics.

The last decade has seen a true explosion of "limit-shape" results. New tools of combinatorics, random matrices and representation theory have given us new models for which limit shapes can be determined and further studied: dimer models, polymer models, sorting networks, ASEP (asymmetric exclusion processes), sandpile models, bootstrap percolation models, polynuclear growth models, etc. The goal of the workshop is to attempt to confront this "ZOO" of combinatorial examples with older foundational work and develop a better understanding of the general limit shape phenomenon.

31.GME'2015 — Graph Modelling in Engineering
 Dates 22 Jun 2015 → 24 Jun 2015
[ID=613575] Go to top of page
 LocationBielsko-Biala, Poland
 Abstract The 3-rd Conference on graph theory applications and modelling in versatile engineering sciences. Continuation of traditions of the conferences Graphs and Mechanics 1993 and 1999. The idea of the conference is to unite all graph applications in mechanial engineering, civil engineering, organization of production, logistics and mechatronics. All graphs and graph related stuctures are taken into account e.g. matroids, generalized networks, Petri networks, graph grammars e.t.c. Graph is an idea connecting fields and simultaneously it is more narrow then 'general indstrial mathematics' or 'mathematical modelling' - using e.g. differential equations. There are some conferences for bond graphs or graph grammars - only. We would like to join all these directions of investigations.
 Topics mechanical engineering, civil engineering, mechatronics, biomechanics, design theory, robotics, graphs, hypergraphs, bond graphs, graph grammars, enumeration, analysis, synthesis, design, isomorphism, decomposition, decision trees, computer tools for graphs, graphs and CAD interaction
