##### Sage Days: Multiple Dirichlet Series, Combinatorics, and Representation Theory

Feb 11 - 15, 2013

Sage is a mathematics software system developed by and for the mathematics community, whose mission is to create a viable free open source alternative to Magma, Maple, Mathematica and Matlab. Its wide span of features, in particular in number theory, combinatorics, and representation theory, together with its friendly community based development, fosters collaborations across disciplines, from the design and implementation of new computer exploration tools to research.

This workshop will bring together experienced Sage and Sage-Combinat developers and experts of multiple Dirichlet series and computational algebraic combinatorics. Like every workshop in the Sage Days series, it will welcome whoever wants to discover Sage, learn more about it, or contribute to it.

As the first meeting for the ICERM Semester... (more)

##### Whittaker Functions, Schubert calculus and Crystals

Mar 4 - 8, 2013

Schubert calculus is the modern approach to classical problems in enumerative algebraic geometry, specifically on flag varieties and their many generalizations. Crystals are combinatorial tools based on quantum groups which arise in the study of representations of Lie algebras. Whittaker functions are special functions on Lie groups or p-adic groups, for example GL(n,F) where F might be the real or complex numbers, or a p-adic field.

The area of intersection between these three topics is combinatorial representation theory. Common tools such as Demazure operators, the Bruhat partial order, and Macdonald polynomials appear in all three areas. Some connections between these three areas are quite new. This workshop will explore these connections.

##### Public Lecture: Scratching the Surface in Dynamic Visual Effects

Mar 11, 2013

Computational physics now underlies some of the most amazing and most routine of visual effects work, using numerical models to simulate reality and more on the computer. Natural-looking water, smoke, fire, and clothing effects in film are often handled best by understanding and solving the physics of how they move in nature. Making simulations efficient and artist-friendly remains a huge challenge.

Dr. Bridson will discuss both the general context of physics-based animation in graphics, but then focus particularly on the advent of new geometric and numerical algorithms for exploiting surface meshes in simulation - both the obvious like clothing and the more surprising like smoke.

##### Combinatorics, Multiple Dirichlet Series and Analytic Number Theory

Apr 15 - 19, 2013

Recent years have seen a flurry of activity in the field of Weyl group multiple Dirichlet series. Surprising and unexpected connections between these multiple Dirichlet series and several different fields of mathematics have emerged. This workshop will survey recent results and set the stage for future developments which further interrelate analytic number theory, automorphic forms and combinatorial representation theory.

Particular focus will be given to applications of Weyl group multiple Dirichlet series to the following areas:

- Average value and nonvanishing results for families of L-functions
- Periods of automorphic forms
- Connections between characters sums over function fields and characters of affine root systems
- Metaplectic Casselman-Shalika formulae and deformations of the Weyl character formula

##### Issues in Solving the Boltzmann Equation for Aerospace Applications

Jun 3 - 7, 2013

Being central to gas dynamics, the Boltzmann equation describes gas flows at the microscopic level in regimes from free molecular to continuum. Its descriptive power makes it indispensable for predicting non-continuum phenomena in gases when experimental data is limited or not available. The Boltzmann equation is used in a wide range of applications, from external aerodynamics and thruster plume flows to vacuum facilities and microscale devices. Accurate solution of the Boltzmann equation for modeling gas flows arising in aerospace applications continues to be a challenge. Existing numerical capabilities fall short of capturing the complexities of engineering design. Reasons for this range from the absence of mathematical models that capture the physics properly to higher dimensionality of kinetic models and the resulting high cost of computations to the failure of mathematical theories to handle complex geometries of real life applications.

The goal of this workshop is to facilitate... (more)

##### Low-dimensional Topology, Geometry, and Dynamics

Sep 9 - Dec 6, 2013

The program focuses on the recent impact of computation and experiment on the study of the pure mathematics sides of topology, geometry, and dynamics. Specific areas include 3-dimensional topology, the study of locally symmetric spaces, low-dimensional dynamics, and geometric group theory. Included are areas where computation has not yet had an impact, but might do so in the near future.

##### Exotic Geometric Structures

Sep 15 - 20, 2013

This workshop will focus on recent advances in the study of geometric structures and their associated group representations. As well as featuring hyperbolic structures, the workshop will also consider more exotic structures, such as projective structures, complex hyperbolic and spherical CR-structures and locally homogeneous space-times. A related focus includes aspects of coarse or non-positively curved geometry such as Gromov hyperbolic spaces and CAT(0) complexes. We will explore the interaction between experimental evidence and rigorous proof.

##### MPE2013 Simons Public Lecture by L. Mahadevan - On Growth and Form: Mathematics, Physics and Biology

Sep 24, 2013

The diversity of living forms led Darwin to state that it is "enough to drive the sanest man mad". How can we describe this variety? How can we understand the origin and evolution of these "endless forms most beautiful?" And how do these forms link to function and physiology at the organismic level and beyond?

Mathematics, and geometry in particular, provides a natural language to express these questions and answer them. Motivated by biological observations on different scales from molecules to organisms to swarms, I will show how a combination of quantitative experiments, physical analogies, mathematical theories and computational models allow us to begin to unravel the mechanistic basis for aspects of morphogenesis and thence towards physiology, pathophysiology and biomimetics.
