Neural Theories of Cognition
Organizers: David Eisenbud (MSRI  Mathematical Sciences Research Institute), Adrienne Fairhall (University of Washington), John Maunsell (University of Chicago), Bruno Olshausen (University of California, Berkeley)The objective of the meeting is to bring theorists and theoreticallymotivated experimentalists together to discuss promising theoretical frameworks for understanding cognitive processes and how these may be brought to bear on interpreting neural data or formulating new experiments. We hope that this meeting will be a chance to discuss future goals for theory in neuroscience: what are missing areas and emerging approaches that might help the field to make real progress in developing theories of brain function.

Recent developments in microlocal analysis
Organizers: LEAD Pierre Albin (University of Illinois at UrbanaChampaign), Nalini Anantharaman (Université de Strasbourg), Colin Guillarmou (Université de Paris XI (ParisSud))Microlocal analysis provides tools for the precise analysis of problems arising in areas such as partial differential equations or integral geometry by working in the phase space, i.e. the cotangent bundle, of the underlying manifold. It has origins in areas such as quantum mechanics and hyperbolic equations, in addition to the development of a general PDE theory, and has expanded tremendously over the last 40 years to the analysis of singular spaces, integral geometry, nonlinear equations, scattering theory, hyperbolic dynamical systems, probability… As this description shows microlocal analysis has become a very broad area. Due to its breadth, it is a challenge for researchers to be aware of what is happening in other parts of the field, and the impact this may have in their own research area. The purpose of this workshop is thus to bring together researchers from different parts of microlocal analysis and its applications to facilitate the transfer of new ideas.

Berlekamp Memorial Workshop on Combinatorial Games
Organizers: Svenja Huntemann (Carleton University), Richard Nowakowski (Dalhousie University), Aaron Siegel (Airbnb)Elwyn Berlekamp (19372019) was a pioneering contributor to combinatorial game theory, greatly advancing the subject over the course of a more than fivedecade career. Along with his coauthors, John Conway and Richard Guy, Berlekamp invented the modern form of the theory, with the publication of Winning Ways for Your Mathematical Plays in 1982. His later work substantially advanced our understanding of the mathematical structure of wellknown games such as Go, Amazons, and DotsandBoxes. More information about his life can be found at www.msri.org/elwyn.
This workshop will be an informal twoday miniconference honoring Berlekamp's work and the subject he helped create. The event will consist of talks, afternoon workshops, and a combinatorial games tournament.Updated on Aug 28, 2019 06:09 PM PDT

Holomorphic Differentials in Mathematics and Physics
Organizers: LEAD Jayadev Athreya (University of Washington), Steven Bradlow (University of Illinois at UrbanaChampaign), Sergei Gukov (California Institute of Technology), Andrew Neitzke (University of Texas, Austin), Laura Schaposnik (University of Illinois at Chicago), Gabriela WeitzeSchmithuesen (Universität des Saarlandes), Anton Zorich (Institut de Mathematiques de Jussieu)Holomorphic differentials on Riemann surfaces have long held a distinguished place in low dimensional geometry, dynamics and representation theory. Recently it has become apparent that they constitute a common feature of several other highly active areas of current research in mathematics and also at the interface with physics. In some cases the areas themselves (such as stability conditions on Fukayatype categories, links to quantum integrable systems, or the physically derived construction of socalled spectral networks) are new, while in others the novelty lies more in the role of the holomorphic differentials (for example in the study of billiards in polygons, special  Hitchin or higher Teichmuller  components of representation varieties, asymptotic properties of Higgs bundle moduli spaces, or in new interactions with algebraic geometry).
It is remarkable how widely scattered are the motivating questions in these areas, and how diverse are the backgrounds of the researchers pursuing them. Bringing together experts in this wide variety of fields to explore common interests and discover unexpected connections is the main goal of our program. Our workshop will be of interest to those working in many different fields, including lowdimensional dynamical systems (via the connection to billiards); differential geometry (Higgs bundles and related moduli spaces); and different types of theoretical physics (electron transport and supersymmetric quantum field theory).

Symposium in Honor of Julia Robinson’s 100th Birthday
Organizers: Hélène Barcelo (MSRI  Mathematical Sciences Research Institute), Thomas Scanlon (University of California, Berkeley), Carol Wood (Wesleyan University)A Symposium on the occasion of Julia Robinson’s 100th birthday will be held on Monday December 9, 2019 at MSRI. Julia Robinson (19191985) was a leading mathematical logician of the twentieth century, and notably a first in many ways, including the first woman president of the American Mathematical Society and the first woman mathematician elected to membership in the National Academy of Sciences. Her most famous work, together with Martin Davis and Hilary Putnam, led to Yuri Matiyasevich's solution in the negative of Hilbert’s Tenth Problem, showing that there is no general algorithmic solution for Diophantine equations. She contributed in other topics as well. Her 1948 thesis linked the undecidability of the field of rational numbers to Godel’s proof of undecidability of the ring of integers. Confirmed participants in this daylong celebration of her work and of current mathematics insprired by her research include: Lenore Blum, who will give a public lecture, Lou van den Dries, Martin Davis, Kirsten Eisentrager, and Yuri Matiyasevich.

Critical Issues in Mathematics Education 2020: Today’s Mathematics, Social Justice, and Implications for Schools
Organizers: Meredith Broussard (New York Unviersity), Michael Driskill (Math for America ), Moon Duchin (Tufts University), Jordan Ellenberg (University of WisconsinMadison), Cliff Freeman (The Young People's Project), Nicole Joseph (Vanderbilt University), Luis Leyva (Vanderbilt University), Yeshi Milner (Data for Black Lives), LEAD Katherine Stevenson (California State University, Northridge), William Tate (Washington State University in St. Louis)Sophisticated computational and quantitative techniques drive important decisionmaking in modern society. Such methods and algorithms are meant to improve the efficiency with which we work and the ways in which we live. An understanding the mathematical underpinnings of these techniques can be used either to disrupt or to purpetuate inequities, and thus such knowledge constitutes power in the modern world. How does this powerful knowledge get used for the common good and get passed on to our children equitably? What does it imply about the kinds of mathematical skills, practices, and dispositions students should learn in schools, colleges, and universities?

Introductory Workshop: Random and Arithmetic Structures in Topology
Organizers: Jeffrey Brock (Brown University), Michelle Bucher (Université de Genève), LEAD Alan Reid (Rice University)The use of dynamical invariants has long been a staple of geometry and topology, from rigidity theorems, to classification theorems, to the general study of lattices and of the mapping class group. More recently, random structures in topology and notions of probabilistic geometric convergence have played a critical role in
testing the robustness of conjectures in the arithmetic setting.
In this introductory workshop, we will bring together junior and senior researchers in order to provide a mix of introductory lectures as well as reporting on more recent progress in topics from this diverse range of subjects.Updated on Jun 17, 2019 08:13 AM PDT
