Meetings/Workshops on Algebra in the United States (USA)

University of Utah

The study of Riemann surfaces and their moduli spaces brings together disparate fields including geometry, topology, dynamics and algebra. This weekend conference will include two mini-courses by Dawei Chen and Chris Leininger focusing on the algebraic and geometric aspects of this topics and two research talks by Diana Davis and Chaya Norton. The intended audience for this conference is early career mathematicians, especially advanced graduate students and postdocs.

This workshop will survey notable developments and applications of higher category theory; it will be a venue for end-users to share their vision of how to apply the theory, as well as developers to share technical advancements. It will consist of 6 series of 3 lectures, each given by instrumental end-users & developers of higher category theory, together with a few question-answer sessions. Each lecture series will be tailored to a diverse audience, accessible to graduate students and non-expert researchers with some background in homological also algebra. The content of these lecture series will concern the following topics.

A one day conference on the interactions of algebra, geometry and combinatorics. Some NSF supported funding is available for graduate students and postdocs to travel to the event.

This workshop celebrates the work of G.T. Whyburn Professor of Mathematics Brian J. Parshall and his collaborators. In the course of his career, together with Ed Cline and Leonard Scott (CPS) as well as with others, Brian has made important contributions to the representation theory of algebraic and quantum groups. The workshop is held on the occasion of his retirement.

Simons Center for Geometry and Physics, Long Island, NY

The theme of the workshop is structural properties of Lagrangian Floer theory and its applications. Topics will include the behavior of Floer cohomology under various kinds of surgery; formulas for the behavior of disk potentials under Lagrangian surgery or mutation; potentials with values in the Chekanov-Eliashberg dg-algebra with loop space coefficients; techniques for showing unobstructedness of Lagrangians; the construction of generators of the Fukaya category; equivariant Floer theory and relations to vortex invariants; and the classification and construction of Lagrangian submanifolds. The goal of this workshop is to develop a community of junior and senior researchers in Lagrangian Floer theory.

Mathematical Sciences Research Institute (MRSI)

This workshop will focus on recent developments in factorization homology, parametrized homotopy theory, and algebraic K-theory. These seemingly disparate topics are unified by a common methodology, which leverages universal properties and unforeseen descent by way of higher category theory. Furthermore, they enjoy powerful and complementary roles in application to the cyclotomic trace.

Algebraic Geometry

This workshop, sponsored by AIM and the NSF, will be devoted to bringing together physicists and mathematicians to concentrate on a variety of problems concerning special holonomy compactifications of M-theory.

This workshop, sponsored by AIM and the NSF, will explore the applications to chromatic homotopy and algebraic K-theory of the new computational techniques in equivariant stable homotopy. The recent renaissance in equivariant stable homotopy theory has provided several new tools which allow us to better understand classical problems and carry out new computations.

University of Nebraska-Lincoln

We are pleased to announce a conference to celebrate the many accomplishments of Professor Brian Harbourne. The conference will feature plenary talks by experts in algebraic geometry and commutative algebra as well as shorter talks or posters by recent PhDs.

This conference is part of the Shanks Workshops held at Vanderbilt University and will take place on May 18 and May 19 2020. The topics will focus on new developments around the area of partitions, and especially ranks, cranks, and other partition statistics. This will especially focus on the interaction between this field and modular type objects.

The goal is to air fresh perspectives and open problems in combinatorics and algebra, those that the speakers think will be important for the future.

Mathematical Sciences Research Institute (MSRI)

The purpose of the summer school will be to introduce graduate students to effective methods in algebraic theories of differential and difference equations with emphasis on their model-theoretic foundations and to demonstrate recent applications of these techniques to studying dynamic models arising in sciences. While these topics comprise a coherent and rich subject, they appear in graduate coursework in at best a piecemeal way, and then only as components of classes for other aims. With this Summer Graduate School, students will learn both the theoretical basis of differential and difference algebra and how to use these methods to solve practical problems. Beyond the lectures, the graduate students will meet daily in problem sessions and will participate in one-on-one mentoring sessions with the lecturers and organizers.

This workshop, sponsored by AIM and the NSF, will be devoted to the study of the geometry and arithmetic of moduli spaces associated to dynamical systems on algebraic varieties, with a particular emphasis on dynamical systems on projective space.

Mathematical Sciences Research Institute (MSRI)

The study of nonnegative polynomials and sums of squares is a classical area of real algebraic geometry dating back to Hilbert's 17th problem. It also has rich connections to real analysis via duality and moment problems. In the last 15 years, sums of squares relaxations have found a wide array of applications from very applied areas (e.g., robotics, computer vision, and machine learning) to theoretical applications (e.g., extremal combinatorics, theoretical computer science).

Northwestern University, Evanston, IL

The goal of this summer school is to introduce participants to tools and ideas from algebraic topology and homotopy theory that are used in the study of fixed point theory. The workshop will be centered around mini-courses, both on classical fixed-point theory and on modern techniques such as duality theory, spectra, and trace methods in algebraic K-theory.

The intended audience for this summer school should be familiar with the material in Hatcher (except the appendices). This reflects our goal that the school be accessible to second and third year students with an interest in algebraic topology from any PhD granting institution. The school will be structured around a few mini-courses, which will run in an active-learning style.

Geometry and Topology,    Courses and Events for Physics Students

University of Michigan in Ann Arbor

ICERM

The structure of free resolutions plays an important role in analyzing singularities of varieties of low codimension. Codimension two Cohen-Macaulay varieties (resp. codimension three Gorenstein varieties) come from rank conditions on an n x (n+1) matrix (resp. a skew-symmetric (2n+1) x (2n+1) matrix). This workshop seeks to push such results to Cohen-Macaulay varieties of codimension three and Gorenstein varieties of codimension four.

American Institute of Mathematics (AIM)

This workshop, sponsored by AIM and the NSF, will be devoted to algorithmic randomness and its applications.

This workshop, sponsored by AIM and the NSF, will be devoted to Ehrhart polynomials and quasi-polynomials. These objects are invariants of lattice and rational polytopes that are the focus of Ehrhart Theory.

Mathematical Sciences Research Institute (MSRI)

The study of discrete subgroups of Lie groups and the associated locally symmetric manifolds has a long and rich history, with powerful interconnections between the geometry of the locally symmetric space, topology of towers of its finite covers, and number-theoretic aspects. More recently dynamical and probabilistic techniques have been fruitfully employed to study these groups and spaces. The workshop will take stock of recent developments in these highly active fields from a variety of backgrounds.

Society for Industrial and Applied Mathematics (SIAM)

Linear algebra is an important area of mathematics and it is at the heart of many scientific, engineering, and industrial applications. Research and development in linear algebra include theoretical studies, algorithmic designs and implementations on advanced computer architectures, and applications to various disciplines. The SIAM Conferences on Applied Linear Algebra, organized by SIAM every three years, are the premier international conferences on applied linear algebra, which bring together diverse researchers and practitioners from academia, research laboratories, and industries all over the world to present and discuss their latest work and results on applied linear algebra.

Mathematical Sciences Research Institute (MSRI)

This workshop will focus on the integrable aspect of random matrix theory and other related probability models such as random tilings, directed polymers, and interacting particle systems. The emphasis is on communicating diverse algebraic structures in these areas which allow the asymptotic analysis possible. Some of such structures are determinantal point processes, Toeplitz and Hankel determinants, Bethe ansatz, Yang-Baxter equation, Karlin-McGregor formula, Macdonald process, and stochastic six vertex model.
