A tentative program is as follows. Motivation: why stacks are needed. Basic example: moduli of curves of genus g. The 2-category of groupoids, schemes as functors, categories fibered in groupoids, pseudofunctors. The stack condition. Representable morphisms, definition of algebraic stack (in the sense of Deligne-Mumford). Quotient stacks, stacks associated to groupoids. The 2-category of stacks; open, closed substacks; topological space associated to a stack. Properties of stacks and of their morphisms; valuative criteria for separatedness and properness. Inertia stack. (Quasi)coherent sh

Résumé: This four-day program will be an introduction to the main themes of the analysis of singular spaces program, geared toward graduate students and postdocs.

Résumé: This congress follows the previous AHA, which where held in Iran (Babolsar 2005), Greece (Samotraki 2002, Xanthi 1990), Italy (Taormina 1978, 1983, 1999, Udine 1985), Taomania (Iasi 1993) and Czech Republic (Prague 1996). Union of Czech Mathematicians and Physicists will organize this congress with the collaboration of the University of Defence. AHA 2008 aims to provide a forum for researchers and practitioners to present their work and to exchange their views on developments and future directions.

Résumé: This is the first official meeting of the working group on Mathematical Fuzzy Logic ( http://www.cs.cas.cz/mathfuzzlog/ ). Mathematical Fuzzy Logic is a subdiscipline of Mathematical Logic which studies the notion of comparative truth. The assumption that 'truth comes in degrees' has revealed very useful in many, both theoretical and applied, areas of Mathematics, Computer Science and Philosophy. The main goal of this meeting is to foster collaboration between researchers in the area of Mathematical Fuzzy Logic, and to promote communication and cooperation with members of neighbouring fields.

Résumé: The University of Colorado at Colorado Springs will host the 2008 Southern Regional Algebra Conference. The conference this year will in particular honor the 70th birthday and retirement of Professor K. M. Rangaswamy. We will follow the usual SRAC format of 25 minute talks. As usual, there is no financial support provided by the host institution for SRAC participants. The conference is open to all interested participants. Algebraists from the Southern Region of the United States are encouraged to attend. Talks in all areas of algebra are welcome, but especially in those areas related to Professor Rangaswamy's work. Deadline for abstracts is August 15, 2008. For more specific information visit the conference website at http://www.uccs.edu/~math/News/RangafestMain.htm , or contact the conference organizer, Gene Abrams, at abrams@math.uccs.edu or 719-262-3182.

Résumé: Aims to bring together leading experts as well as young researchers working on topics mainly related to univalent functions and Geometric Function Theory with applications in various area of mathematics, and to present their recent work to the mathematical community. English is the official language of the symposium.

Résumé: There have been some very rapid changes to the interactions of algebra, geometry and analysis in recent years, many prompted by new mathematical ideas coming from physics. Novel algebraic structures have been invented, new methods for calculating invariants of geometric objects found and radical developments in noncommutative algebra and analysis have occurred under the influence of string theory and many body quantum physics. This meeting is to review these rapidly developing areas, so as to provide an additional attraction for international visitors who may be interested in attending the AustMS/NZMS convention. It also provides opportunities to postgraduate students and postdoctoral fellows to access these latest developments and to relate them to their own research.

Résumé: This workshop, sponsored by AIM and the NSF, will be devoted to the study of nonnegative matrices and their generalizations. The goal is to make progress both in specific areas and on the global themes that unify this subject.

Résumé: The programme will focus on a number of aspects which are likely to become of major importance for subsequent developments, such as: the connection between integrable dynamical maps and the algebraic geometry of rational surfaces, the issue of irreducibility of nonlinear special functions defined through discrete equations and the underlying Galois theory of difference equations, the underlying spectral theory and isomonodromic deformations of linear difference equations, the connection with modern developments in representation theory such as cluster algebras and affine Weyl groups, the emergence of Diophantine problems of number theory and p-adic analysis in connection with the integrability of analytic difference equations, the problem of finding symmetries and conservation laws for discrete systems, and the primary role discrete integrable systems play in quantum mechanics, in particular quantum groups and quantum field theory on the space-time lattice.

Résumé: The main theme of the workshop will be to explore modern approaches to problems originating in Classical Algebraic Geometry, and at the same time offer an introduction to various subfields to the younger participants in the semester-long program. Topics will include: (1) Birational geometry; (2) Moduli spaces of curves; (3) Moduli spaces of vector bundles; (4) Abelian varieties.

Résumé: TOPOLOGY, C*-ALGEBRAS, and STRING DUALITY May 18 - May 22, 2009 Opening reception on the evening of May 17 at Texas Christian University, Fort Worth, TX Principal Lecturer: Jonathan Rosenberg (Univ. of Maryland) Some of the most exciting current research in geometry and topology has been motivated by problems in mathematical physics in general, and string theory in particular. Physicists are still divided concerning the usefulness of string theory as a ``unified field theory,'' uniting our understanding of all the fundamental forces of nature. However, even if string theory should turn out not to be fully confirmed by experiment, the fascinating and beautiful mathematics it has generated is expected to retain its mathematical value. The subject of the conference will involve a number of such ``spin-offs'' of string theory into pure mathematics, and the way they connect with other topics in topology and operator algebras that were initially developed for other purposes.

Résumé: This will be the 19th annual PCMI Summer Session for research mathematicians, graduate students, undergraduate students, undergraduate faculty, and secondary school teachers.

Résumé: The conference will consist of a series of invited lectures concerning applications of the Stone-Cech compactification of the natural numbers and other discrete semi-groups to Algebra, Analysis and Combinatorics. The conference is also an opportunity to celebrate the immense contribution to this field that has been made by Dona Strauss on the occasion of her 75th Birthday. Talks are by invitation only. However the organizers would like to invite everyone who is interested to attend. The following have agreed to speak at the conference: Mathias Beiglbck (Vienna University of Technology, Wien); Vitaly Bergelson (Ohio State University); Wis Comfort (Wesleyan University); Garth Dales (University of Leeds); Stefano Ferri (Universidad de los Andes, Bogot); Chris Good (University of Birmingham); Neil Hindman (Howard University); Anthony To-Ming Lau (University of Alberta); Imre Leader (University of Cambridge); Matthias Neufang (Carleton University); Igor Protasov (Kyiv Unive

Résumé: The theme of the meeting will be 'Banach algebras and their applications'.

Résumé: This workshop, sponsored by AIM and the NSF, will be devoted to the study of the relative trace formula and periods of automorphic forms. In particular, we hope to formulate a precise general conjecture for the exact value of period integrals which encompasses all known and conjectured cases.
