Speaker: Marina Moleti Scuola Internazionale Superiore di Studi Avanzati (SISSA) Abstract:We present a new algorithm to extract the quiver and superpotential of a broad class of threefolds that fall under simple threefold flops. These geometries are generally non-toric and can be viewed as monodromic fibrations over a complex plane of deformed ADE singularities. We illustrate how the quantum field theory of a D2 brane probing these spaces captures their non-commutative resolution (NCCR).

Speaker: Guillaume Laplante-Anfossi (University of Southern Denmark) Abstract:Given a curved A-infinity algebra and a bounding cochain (a.k.a Maurer—Cartan element), one can twist the former by the latter to get a new A-infinity algebra where the curvature is zero. This uncurving procedure plays a central rôle in Floer theory, where Fukaya categories are naturally curved objects. The goal of this talk will be to give a universal characterization of the procedure, using the theory of operads: we will show that the operad cMC, whose algebras are curved A-infinity algebras endowed with a Maurer—Cartan element, together with its natural morphism to the A-infinity operad, is terminal in a certain comma category. This category does not contain the Maurer—Cartan equation, thus the theorem provides a way to « rediscover » it as the answer to a universal (algebraic) problem. This is joint work with Adrian Petr and Vivek Shende.

Speaker: Michael Borinsky The Institute for Theoretical Studies (ETH-ITS), Zürich Abstract:I will present new results on the asymptotic growth rate of the Euler characteristic of Kontsevich's commutative graph complex. These results imply the same asymptotic growth rate for the top-weight Euler characteristic of M_g, the moduli space of curves, due to a recent work by Chan, Galatius and Payne. Further, they establish the existence of large amounts of unexplained cohomology in this graph complex. I will explain the role of this graph complex from the perspective of M_g's cohomology.
