Welcome to MathMeetings.net! This is a list for research mathematics conferences, workshops, summer schools, etc.

There are a few other conference lists available, but this list
aims to be more complete by allowing *anyone at all* to add
announcements. Rather than use a wiki, announcement information is
stored in database format so that useful search functions can be
added as the list grows.

This site began as AlgTop-Conf, for meetings in algebraic topology. It is now expanded to serve other mathematics subjects. Use tag filtering to focus on announcements related to your discipline (see right or below).

#### Updates 2016-01

- Now filter announcements by subject tags
- Form for editing announcements is now the same as that for adding new announcements
- New 'view' page for each announcement, and announcement data in confirmation emails
- Select boxes improved with select2 (jquery)

# Upcoming Meetings

## September 2017

### Locally Symmetric Spaces: Analytical and Topological Aspects

Meeting Type: long-term research program

Contact: see conference website

### Description

During the 2017-18 academic year, the School will have a special program on Locally Symmetric Spaces: Analytical and Topological Aspects. Akshay Venkatesh of Stanford University will be the Distinguished Visiting Professor.

The topology of locally symmetric spaces interacts richly with number theory via the theory of automorphic forms (Langlands program). Many new phenomena seem to appear in the non-Hermitian case (e.g., torsion cohomology classes, relations with mixed motives and algebraic K-theory, derived nature of deformation rings). One focus of the program will be to try to better understand some of these phenomena.

Much of our understanding of this topology comes through analysis ("Hodge theory"). Indeed harmonic analysis on locally symmetric spaces plays a foundational role in the theory of automorphic forms and is of increasing importance in analytic number theory. A great success of such harmonic analysis is the Arthur-Selberg trace formula; on the other hand, the analytic aspects of the trace formula are not fully developed, and variants such as the relative trace formula are not as well understood. Thus analysis on such spaces, interpreted broadly, will be another focus of the program.

### Geometric topology in low dimensions

Meeting Type: conference

Contact: see conference website

### Description

The resolution of many of Thurston's prophetic questions about the structure of 3-manifolds has generated a vast array of techniques which permeate many of the areas covered by the symposium.

As is often the case, the resolution of old conjectures has led to intriguing new questions, which will be the focus of this workshop. Examples include: given a combinatorial or arithmetic presentation of a 3--manifold, describe its geometric structure concretely (''effective geometrisation''); understand the geometry of the Thurston unit norm ball, for example how it behaves under taking towers of covers; understand the connection between Heegard-Floer homology and orderability of fundamental groups. Several old conjectures, such as the simple loop conjecture for surfaces in three-manifolds and the conjecture that a quasifuchsian group is determined by its pleating laminations, continue to motivate work.

Links with other workshop areas include a renewed focus on computation in 3-manifold theory, the use of special cube complexes via the Agol-Wise machinery, used to resolve several of the conjectures which remained after Perelman's solution to the Geometrisation conjecture, and the geometry and combinatorics of complexes of discs and spheres in 3-manifolds, which have been used to investigate the structure of outer automorphism groups of free groups.

David Shea Vela-Vick (LSU)

* there will be a slight-but-negligible variance in talk lengths

Also, the departmental Colloquium on Nov. 9th will be given by

Saul Glasman (Minnesota).

Additionally, the conference will have 7 student talks that are 15- or 20-minutes long for advanced undergraduates and Master's-level students advancing to a Ph.D. to be done not at their current institution. There will be 3 prizes of $125, $100, and $75 for these talks. Further planning for them is underway, with priority given to students at speakers' institutions.

The conference will start on Friday (the 10th) around 1 p.m. and end on Sunday around noon/12:15 p.m.

Information about the conference, as it becomes available, will be posted at

https://math.louisiana.edu/node/181.

Some more information about the conference and UL follows.

In the Carnegie classification, UL is designated as having "Higher Research Activity" and, in the NSF's 2015 HERD rankings for the mathematical sciences, UL's math department was 80th.

The conference budget is modest: our annual tradition since 1970 is that, while there isn't funding for the travel and lodging expenses of speakers and participants, there will be nice (perhaps "classical and contemporary") Cajun-style dinners on Friday and Saturday nights (respectively) provided for by the Lloyd Roeling Conference Fund and the Math Dept.

Best regards,

Daniel, on behalf of the Organizing Committee:

Scott Bailey (Clayton State), Daniel Davis (UL),

Robin Koytcheff (UL), and Peter Oman (Southeast Missouri State)

### 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.

## March 2019

### Derived algebraic geometry and its applications

### Description

This workshop will bring together researchers at various frontiers, including arithmetic geometry, representation theory, mathematical physics, and homotopy theory, where derived algebraic geometry has had recent impact. The aim will be to explain the ideas and tools behind recent progress and to advertise appealing questions. A focus will be on moduli spaces, for example of principal bundles with decorations as arise in many settings, and their natural structures.
