1.ICERM Semester Program: Phase Transitions and Emergent Properties |

Termin | 02. Feb 2015 → 08. Mai 2015 | [ID=592142] |

Ort | Providence, Vereinigte Staaten |

Zusammenfassung | 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 different 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. |

3.ICERM Workshop: Limit Shapes |

Termin | 13. Apr 2015 → 17. Apr 2015 | [ID=592161] |

Ort | Providence, Vereinigte Staaten |

Zusammenfassung | 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. |

4.28th Cumberland Conference on Combinatorics, Graph Theory and Computing |

Termin | 15. Mai 2015 → 17. Mai 2015 | [ID=706767] |

Ort | University of South Carolina, Columbia, Vereinigte Staaten |

Zusammenfassung | The Cumberland Conference on Combinatorics, Graph Theory, and Computing is an annual conference that brings together internationally known researchers, industrial mathematicians and computer scientists, and southeastern university and college professors, post-docs, graduate and undergraduate students, to discuss the latest advances in discrete mathematics and computer science. Particular efforts are made to include faculty and students from smaller institutions throughout the region. Each year, a different university in the Cumberland region hosts the conference, usually in the month of May, immediately after the end of the spring semester. |

6.8th International Conference on Lattice Path Combinatorics & Applications |

Termin | 17. Aug 2015 → 20. Aug 2015 | [ID=679347] |

Ort | Pomona, California, Vereinigte Staaten |

Zusammenfassung | 8th International Conference on Lattice Path Combinatorics & Applications. Researchers from all over the world come and present their work relating to lattice path combinatorics. These conferences were originally founded and organized (with loving care) by Sri Gopal Mohanty. For the most part, talks are presented sequentially over a 3-4 day period.
Sometimes tutorial sessions and special workshops are included on the program. Participants include a nice mix of regulars from past conferences and new reseachers who are warmly welcomed as part of the family. |

Themen | Conference Topics to be covered include (but are not limited to): • Lattice path enumeration • Plane Partitions • Young tableaux • q-calculus • Orthogonal polynomials • Random walks • Nonparametric statistical inference • Discrete distributions and urn models • Queueing theory • Analysis of algorithms • Graph Theory and Applications • Self-dual codes and unimodular lattices • Bijections between paths and other combinatoric structures |
