22/08/2022 | Workshop

Minimal surfaces in symmetric spaces and Labourie’s conjecture

The school will focus on minimal surfaces in symmetric spaces, and more specifically on Labourie’s conjecture. The participants (between 20 and 25 participants) will be graduate students, post-docs and young faculty. Following an Arbeitsgemeinschaft format, most of the participants will give a 2-3 hours talk. The organisers will assign the topics and give the necessary references to guide the content of the lectures.

Differential Geometry and Geometric Analysis

The conference will be held in honor of Karsten Grove's 75th birthday.

The conference "Differential geometry and geometric analysis" will take place June 20 to June 24, 2022 in Florence, Italy.

Several major themes have been selected for the conference, including:

- Analysis in metric spaces, Geometric group theory, Geometric measure theory,

- Geometric theory of PDE's, Group actions on Riemannian manifolds, Manifolds of positive and nonpositive curvature,

- Metrics with special holonomy, Minimal manifolds and Min-Max Theory, Ricci Flow.

Arithmetic groups and 3-manifolds

Arithmetic groups provide a fruitful link between various areas, such as geometry, topology, representation theory and number theory. Methods from geometry and topology hinge on the fact that arithmetic groups are lattices in Lie groups, whereas the theory of automorphic forms establishes a connection to representation theory and number theory. This interplay is especially intriguing in the setting of hyperbolic 3-manifolds. Indeed many conjectures in 3-manifold theory tend to be much more accessible for hyperbolic 3-manifolds whose fundamental groups are arithmetic, and conversely such manifolds provide the simplest set-up in which some of the most exciting new phenomena in the Langlands program can be studied

Geometry and Analysis on Non-Compact Manifolds

This conference will bring together researchers in Differential Geometry, in Geometric Analysis, and in their applications. The general focus of the conference will be on recent results on manifolds with bounded geometry, on singular stratified spaces and on the geometry and analysis on these spaces. More concretely, we will invite researchers from several areas, including: complete manifolds with special holonomy and their moduli spaces, stratified spaces, index theory on Riemannian and Lorentzian manifolds, spectral theory of geometric differential operators, relations between geometric analysis and conformal geometry, such as the Yamabe problem on singular and non-compact spaces and generalizations thereof. We envision that the interactions between the participants in this Conference will lead to applications to limits and collapse of manifolds with curvature bounds, moduli spaces, general relativity, the wave equation on curved spacetimes, as well as to singular partial differential equations in general. One of the conference's main goals will be to foster interactions between these various areas of mathematics.

Train the Trainer - Mentoring Workshop for Women in Math

Female researchers in mathematics are underrepresented among their peers in most countries and on most career levels. One possible contribution to counteracting this gender gap is to offer specific mentoring programs for women in math in academia. We offer professional training for (prospective) mentors and people interested in setting up a mentoring program. Our focus is on mentoring for women in mathematics (and other theoretical sciences). The interactive mentoring training aims at preparing the participants for their future role as mentors and/or program organizers.
