Abstract: This will be a summary of the closed discussions and an opportunity for everyone to contribute suggestions.

Abstract: This will be a broad talk about coherence of groups, and how it relates to conjectures about hyperbolic groups with planar boundaries. A group is coherent if every finitely generated subgroup is finitely presented. This is a property...

Abstract: There seems to be an analogy between the classes of fundamental groups of compact 3-manifolds and of one-relator groups. (Indeed, many 3-manifold groups are also one-relator groups.) For instance, Dehn’s Lemma for 3-manifolds (proved by...

Abstract: I will survey (in)coherence of lattices in semisimple Lie groups, with a view toward open problems and connections with the geometry of locally symmetric spaces. Particular focus will be placed on rank one lattices, where I will discuss...

This talk will cover sections 2 and 3 of "The symplectic arc algebra is formal" by Abouzaid-Smith

This talk will prove formality results for Fukaya categories in some examples following "The symplectic arc algebra is formal" by Abouzaid--Smith.

This talk is an introduction to the work of Witten on physical approaches to knots, especially based on hep-th 1101.3216. Classical approaches to the Jones polynomial are based on various combinatorial constructions which have the downside of not...

Consider $T^*P^1$ as the B-model of a mirror equivalence. It turns out that the A-model mirror depends on choices and I will describe two of these mirrors: one with underlying symplectic manifold the complement of a conic in $T^*S^2$, and the other...

I will discuss Lipshitz and Sarkar's space level refinement of Khovanov homology. Their approach is combinatorial in nature and is inspired by Cohen-Segal-Jones' construction for Floer homology.

We'll talk about various dimensional reductions of the HW equations and the connections to (de)categorification as we continue explaining their physical origins. Time permitting we will discuss (conjectural?) relations to Fukaya-Seidel categories.

We'll discuss how dimensional reductions of the Haydys-Witten equations are connected to Haydys's definition of the Fukaya-Seidel category. Time permitting we'll touch on connections to Donaldson-Thomas's vision of higher-dimensional gauge theory.
