The Richmond Geometry Meeting will focus on emergent research topics while bringing together researchers in algebraic geometry, low-dimensional topology, and mathematical physics. In summer 2023, we will highlight developments in moduli theory together with new perspectives in Floer homology and low-dimensional topology. This year's format will be in-person. This meeting is supported by NSF award DMS-2240741.

Topic: Motivic homotopy theory involves the study of algebraic varieties and schemes using methods not only from algebraic geometry, but also from algebraic topology. A basic idea is to use techniques from homotopy theory, such as the construction of homotopy groups and the use of homotopical invariants, to investigate topological and geometric properties of these varieties. It was developed in the late 20th century as a way to extend classical homotopy theory, which studies topological spaces up to continuous deformations, to the realm of algebraic geometry.

One of the fundamental problems in motivic homotopy theory over F is to calculate the homotopy groups π_t,w(1) of the motivic sphere spectrum 1. Here the integers t, w ∈ Z refer to the topological degree and the weight, respectively. In a precise sense, these groups are the universal motivic invariants because the motivic sphere is the unit for the tensor product on motivic spectra. All the relations witnessed in the graded ring π_*,*1 hold in every other theory representable in the stable motivic homotopy category, such as algebraic cobordism, algebraic and hermitian K-theory, motivic cohomology, and higher Witt theory.

The goal of the workshop is to discuss “Why, what, and how” on specific computations in stable motivic homotopy theory.

Suggested prerequisites:

Mentors: The 2023 Talbot workshop will be mentored by Prof. Oliver Röndigs of the Osnabrück University and Paul Arne Østvær of University of Milan, Italy and University of Oslo, Norway.

Format: The workshop discussions will have an expository character and a majority of the talks will be given by participants. Breaks will be built into the schedule for informal discussions and collaborations. The workshop will take place in a communal setting, with participants sharing living space and cooking and cleaning responsibilities.

The workshop will be held entirely in-person. Participants should expect to follow mitigation measures such as masking in indoor common spaces and eating meals in a socially distanced/outdoor setting.

Timeline: The 2023 Talbot workshop will take place June 4-10, 2023.

Funding: We cover all local expenses, including lodging and food. We also have limited funding available for participant travel costs.

Who should apply: Talbot is meant to encourage collaboration among young researchers, particularly graduate students. To this end, the workshop aims to gather participants with a diverse array of knowledge and interests, so applicants need not be an expert in the field. In particular, students at all levels of graduate education are encouraged to apply. Our decisions are based not on applicants' credentials but on our assessment of how much they would benefit from the workshop. As we are committed to promoting diversity in mathematics, we also especially encourage women and minorities to apply.

Inclusiveness statement: In accordance with the Statement of Inclusiveness, this workshop will be open to everybody, regardless of race, sex, religion, national origin, sexual orientation, gender identity, disability, age, pregnancy, immigration status, or any other aspect of identity. We are committed to ensuring that the Talbot Workshop is a supportive, inclusive, and safe environment for all participants, and that all participants are treated with dignity and respect.

The above conference is the continuation of the following conferences:

(1) 2006 International Conference on Topology and its Applications,_ June 23-26, 2006, Aegion, Greece.

(2) 2010 International Conference on Topology and its Applications,_ June 26-30, 2010, Nafpaktos, Greece.

(3) 2014 International Conference on Topology and its Applications,_ June 3-7, 2014, Nafpaktos, Greece.

(4) 2018 International Conference on Topology and its Applications,_ July 3-7, 2018, Nafpaktos, Greece.

This conference is organized around the themes of K-theory, (motivic) homotopy theory, topological Hochschild homology, trace methods, and related topics. It is dedicated to Bjørn Ian Dundas on the occasion of his 60th birthday.

Victor P. Snaith (1944 – 2021) was distinguished not just as an outstanding mathematician who made deep and lasting contributions in algebraic topology and number theory but also as a charismatic leader who enthusiastically developed research communities and generously supported young researchers.

The conference will bring together homotopy theory, cohomology of groups, algebraic K-theory and number theory, the main areas in which Vic worked. The aim is to feature important developments, paying special attention to synergies between these areas, as Vic did in much of his versatile research.

A workshop on Algebraic K-theory of spaces and related topics will be held at the University of Regensburg, during July 24-28, 2023.

The goal of this workshop is to bring together researchers in the field, review aspects of the deep interactions between algebraic K-theory and manifold topology, and discuss various developments in the field, especially, from the perspective of the algebraic K-theory of spaces and its varied connections.

This is a residential summer school on the theme of translating notions in manifold topology to a symplectic setting.

It will take place Wednesday through Sunday, 16-20 August 2023, in Paradise Valley, Montana.

All participants must register; the registration deadline is 30 April 2023.*

• We are happy to work with anybody needing to finalize their travel plans before, or after, this deadline.

Description.

The three Scientific Organizers will deliver lecture series on the theme of translating notions and results from manifold topology into a symplectic setting.

For example, given a sheaf on a manifold X, one can associate its micro-support (or singular support) which is a conic Lagrangian subset of the cotangent bundle TX. In this way, one is led to the idea that the category of sheaves on X naturally localizes over TX. Replacing cotangent bundles T*X with more general symplectic manifolds (for example, Liouville or Weinstein manifolds) leads to the theory of micro-local sheaves, a topological approach to the Fukaya category. These notions have important applications, notably in the areas of mirror symmetry and geometric representation theory.

The presentations will be targeted to novices in the field, such as advanced graduate students or postdocs, in the spirit of creating new colleagues. A working familiarity with algebraic topology and differential geometry (at the level of a graduate sequence), as well as some category theory, will be helpful.

The workshop’s schedule will allow for mid-day discussions and walks & hikes.

See the summer school's webpage for more information.

The BTM will be preceded by an Early Careers Conference, to take place on the afternoon of Tuesday 5th September and the morning of Wednesday 6th September, aimed at PhD students and other early career topologists.

This conference is focused on the topics of moduli spaces, including configuration spaces and hyperplane arrangements, braid groups, mapping class groups and quantum representations. The goal is to bring together researchers working in different areas under the general umbrella of "moduli spaces" and to encourage the discovery of new connections between these areas.
