Combinatorial Categories in Algebra and Topology

ac.commutative-algebra at.algebraic-topology co.combinatorics
2018-11-22 through 2018-11-24
Osnabrueck University, Institute of Mathematics
Osnabrueck; Germany

Meeting Type: workshop

Contact: Tim Roemer, Oliver Roendigs, Markus Spitzweck

Description

This workshop concerns prominent indexing categories with applications to interesting problems in commutative algebra and algebraic topology. The prime example sparking our interest is the work of Snowden, Church, Ellenberg and others on GL-structures and FI-modules, which involves variations on categories of finite sets and injections. These occur prominently in algebraic topology whenever algebraic structures up to homotopy have to be encoded. Our aim is to bring researchers with different backgrounds but a common interest in special indexing categories together and catalyze a fruitful exchange. Invited speakers include:

  • Rob H. Eggermont (Eindhoven University of Technology, The Netherlands)
  • Moritz Groth (University of Bonn, Germany)
  • Javier J. Gutiérrez (Universidad de Cantabria, Spain)
  • Henning Krause (University of Bielefeld, Germany)
  • Liping Li (Hunan Normal University, China)
  • Ieke Moerdijk (University of Utrecht, The Netherlands)

Meeting Type: workshop

Contact: David Ayala, Oscar Randal-Williams, Ulrike Tillmann, Michael Weiss, Paul Goerss

Description

Part of the Semester Program "Homotopy Harnessing Higher Structures." This programme will highlight four related themes: the new algebraic topology of differentiable manifolds, derived representation theory and equivariant homotopy theory, the interplay between arithmetic geometry and stable homotopy theory, and the analysis of foundations in these new contexts "the homotopy theory of homotopy theory". This workshop will focus on the algebraic topology of manifolds.

Description

The last four decades have revealed many deep connections between topological quantum field theory (TQFT), low-dimensional topology, and geometric structures on manifolds, particularly hyperbolic geometry. This conference will further explore and strengthen these connections by bringing together a distinguished international group of researchers working in or at the interface of these subjects.

Categorification in quantum topology and beyond

2019-01-07 through 2019-01-18
Erwin Schrödinger International Institute for Mathematics and Physics
Vienna; Austria

Meeting Type: conference

Contact: Paul Wedrich

Description

Categorification is a flexible and powerful set of techniques and ideas, which produces insight about mathematical structures by viewing them as shadows of objects in a richer world, often described in terms of higher categories. Two important and interrelated categorification programmes, which are the basis for this workshop, concern the concepts of quantum link homologies and higher representation theory. Both have their origin in mathematics, but have since developed into some of the most fruitful grounds for collaboration between pure mathematics and theoretical physics.

The first week of this workshop will make the recent rapid developments in the areas of quantum link homologies and higher representation theory accessible to non-experts and intensify communication between specialists in these and related areas like gauge theory, TQFT, quantum Teichmüller theory, and string theory. The second week will be used to host a research conference with thematic emphasis on categorification of skein theory and 3-manifold invariants.

Topology of Manifolds: interactions between high and low dimensions

MATRIX Research Institute
Creswick campus; Australia

Meeting Type: Workshop

Contact: Jonathan Bowden, Diarmuid Crowley, Jim Davis, Stefan Friedl, Carmen Rovi, Stephan Tillmann

Description

This meeting will bring together students, postdocs, and researchers from all over the world to stimulate research on fundamental questions in manifold theory. It will promote the interaction between researchers in high and low dimensional topology. The meeting is structured as follows: mini-courses in the first week by world experts (Lueck, Stipsicz, and Teichner) and a conference in the second week. Both weeks focus on open problems and collaborative work. This structure will greatly benefit early career researchers. Another feature of the meeting that will make it accessible is the theme of the program: promoting interactions between high and low dimensions will mitigate the tendency of technical talks and problems. There are two main research aims for this meeting. The first is to identify settings for synergy from the interaction between high and low dimensions and to make progress on problems in these settings. The second is to produce a high-quality problem list to guide future research in manifold topology. It is our hope that a well-crafted and publicized problem list arising from the collaboration during the meeting will be of long-term benefit to the mathematical community.

An n-manifold is a space which locally resembles n-dimensional Euclidean space. Manifolds of dimension less or equal than 3 are studied using geometric techniques. Manifolds of dimension greater or equal than 5 are studied via surgery theory, which involves a mix of algebraic and differential topology, algebra, and analysis. Dimension 4 is in between; both the high dimensional Whitney Trick and the low-dimensional geometric techniques are only partially successful. The need for our program is that these areas have diverged in the last several decades, to the extent that, often researchers in low/middle/high dimensional topology are not always aware of the current research/techniques in other dimensions. This program will, hopefully, lead to a synergy, benefiting both the experts and the new generation of early career researchers.

Derived Algebraic Geometry

Meeting Type: research program

Contact: see conference website

Description

Derived algebraic geometry is an extension of algebraic geometry that provides a convenient framework for directly treating non-generic geometric situations (such as non-transverse intersections in intersection theory), in lieu of the more traditional perturbative approaches (such as the “moving” lemma). This direct approach, in addition to being conceptually satisfying, has the distinct advantage of preserving the symmetries of the situation, which makes it much more applicable. In particular, in recent years, such techniques have found applications in diverse areas of mathematics, ranging from arithmetic geometry, mathematical physics, geometric representation theory, and homotopy theory. This semester long program will be dedicated to exploring these directions further, and finding new connections.

Braids, Resolvent Degree and Hilbert’s 13th Problem

Description

Overview

HIL2019 web imageThe purpose of this workshop is to bring focused attention to Hilbert’s 13th problem, and to the broader notion of resolvent degree. While Abel’s 1824 theorem–that the general degree n polynomial is only solvable in radicals for n<4

is well known, less well known is Bring’s 1786 proof that a general quintic is solvable in algebraic functions of only one variable. Hilbert conjectured that for a general sextic, one needs algebraic functions of two variables, and that for a general degree 7 polynomial, one needs algebraic functions of three variables. More generally, it is natural to expect that as n → ∞ , so does the minimal number of variables needed to solve the general degree n polynomial. In a celebrated theorem, Arnol’d and Kolmogorov proved that, at the level of continuous functions, there is no local obstruction to reducing the number of variables to one. Thus, a resolution of Hilbert’s problem must lie deeper. Resolvent degree was introduced by Brauer in order to provide a rigorous statement of these conjectures. While no progress has yet been made on these conjectures, the study of resolvent degree is receiving renewed attention and an influx of ideas from related fields, including:

the theory of essential dimension
uniformization of moduli spaces
braid monodromy
p-adic Hodge theory

This workshop will bring together young and established researchers who work in these fields to explore topics related to Hilbert’s conjectures, to facilitate interaction between subdisciplines, and to lay the groundwork for future progress. The workshop will be organized around mini-courses by experts which will be aimed at 1) conveying the methods that can be brought to bear from each area, and 2) formulating problems concerning resolvent degree that seem particularly tractable using these methods.
