Konferenzen zum Thema Geometrie und Topologie in den Vereinigten Staaten (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.

University of California, Irvine

Since 1992 UCI and UCSD have run the Southern California Geometric Analysis Seminar. The upcoming 2020 conference will be at UC Irvine. All interested participants are strongly encouraged to register via the online registration form and indicate request for financial support if needed. Financial support if available will be from the US National Science Foundation and priority will be given to graduate students, recent Ph.D.'s, and under-represented minorities.

University of Arkansas, Fayetteville

The Redbud Topology Conference is a regional conference in topology and related areas, with participants from the University of Arkansas, the University of Oklahoma, Oklahoma State University, and elsewhere. The conference this year will focus on algorithmic and effectiveness in 3-manifold topology. The conference will run all day Saturday and all morning on Sunday, ending by 2 PM. There will also be a session on Friday afternoon as a warm-up for graduate students. There will be dinner outing on Saturday evening.

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.

Graphentheorie und Kombinatorik,    Algebra

This workshop, sponsored by AIM, the Simons Foundation, and the NSF, will consider the role of topology in characterizing materials and in the prediction of their physical properties, particularly for two-dimensional material such as graphene. The focus will be on important mathematical questions at the interface of the analysis and topology in the context of the governing fundamental partial differential equations and other models. Two such questions are the bulk edge correspondence and the existence and robustness of edge states in aperiodic settings.

Spring Topology and Dynamical Systems Conferences are a long-running series of annual conferences focusing on several actively researched areas in topology and dynamical systems. Sessions will be held in Continuum Theory, Dynamical Systems, Geometric Topology, Geometric Group Theory, Set-Theoretic Topology, and Topology in Data Science.

This workshop will explore topics of current interest in the theory of Floer homology for 3-manifolds. Floer homology is a powerful tool for studying the topology of 3- and 4-dimensional manifolds, and the relations between them. The first such invariants were introduced by Floer, and arose in the context of Donaldson theory on smooth 4-manifolds.

The new and rapidly expanding area of Analytic Combinatorics in Several Variables (ACSV) concerns enumeration problems in such areas as lattice walks, statistical mechanical models, quantum walks and other exactly solvable models where asymptotic estimation of coefficients of a bivariate or multivariate generating function is required. The multivariate setting incorporates a wider swath of mathematics. including singularity theory, algebraic topology, and computational algebra. Participants in this MRC will be introduced to problems from these areas of mathematics whose solutions have direct applications to ACSV. These problems are not hard to state in the language of disciplines such as Morse theory, harmonic analysis, or commutative algebra, but they ask questions not typical in those fields. A long-term goal is to advance and automate this work, so that its benefits can be used by other researchers in mathematics and the natural sciences through implementations in computer algebra packages. Problems for this MRC will be arranged around five central topics: effective computer algebra methods, algorithms using computational topology, multivariate asymptotic phase transitions, singular transforms for degenerate saddle-point integrals, and applications of harmonic analysis and singularity theory. Researchers with knowledge in any one of these areas are encouraged to apply to this MRC.

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.

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.

This workshop will discuss results and new developments in Leibniz algebras and related topics. This includes and not limited to Lie algebras, homological algebra or non-commutative geometry.

Leibniz algebras, Lie algebras, Homological algebras.

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.

Mathematical Sciences Research Institute (MSRI)

The talks in this workshop will present a wide array of current applications of topology in neuroscience, including classification and synthesis of neuron morphologies, analysis of synaptic plasticity, algebraic analysis of the neural code, topological analysis of neural networks and their dynamics, topological decoding of neural activity, diagnosis of traumatic brain injuries, and topological biomarkers for psychiatric disease. Some of the talks will be devoted to promising new directions in algebraic topology that have been inspired by neuroscience.
