C*-seminar by Henrikke Gedde Rustad (University of Oslo).

I will present details about an ongoing joint work, where we intend to prove derived equivalence between two non-birational Calabi-Yau 3-folds. I will present a summary of the status of classification of CY3s and mirror symmetric motivations that prompt us to specifically study these two 3-folds. I will start with some classical projective geometry where we construct the titular 3-folds, following which I will move on to toric geometry where we showcase preliminary evidence for their derived equivalence. I will end with a discussion of GLSMs which is a relatively modern technique in the landscape of derived categories, which we hope will lead us to our desired proof.

QOMBINE seminar by Lyudmila Turowska (Chalmers University of Technology and University of Gothenburg)

The derived category of a Fano variety will often have a semiorthogonal decomposition consisting of a sequence of exceptional line bundles and a remaining subcategory, which we will call the Kuznetsov category. The categorical Torelli problem asks whether knowing this category up to exact equivalence is enough to determine the variety up to isomorphism. We will explain how a technique based on a computation of the Hochschild-Serre algebra of the category shows that the answer is yes in many cases, including many weighted hypersurface and a Veronese double cone. This is joint work with Xun Lin and Shizhuo Zhang.

Professor Bernt Øksendal is a globally celebrated mathematician and pioneer in stochastic analysis and financial mathematics. His groundbreaking contributions, particularly in stochastic differential equations and their applications, have profoundly influenced research and education. His seminal textbook on stochastic differential equations remains a foundational resource for mathematicians worldwide.

Aldo Solari is Professor of Statistics at the Department of Economics, Ca’ Foscari University of Venice. He holds a degree and Ph.D. in Statistics from the University of Padova and began his academic career at the University of Milano-Bicocca, where he was appointed Professor in 2020. His research centers on the development of statistical methods with applications in biostatistics, genomics, and neuroscience. He has received the Hans van Houwelingen Biometry Award and the Rita Levi Montalcini Award.

Virasoro constraints were recently formulated for moduli of sheaves. The main difference compared to Gromov-Witten theory lies in the linearity of the former which allowed us (B.-Lim-Moreira) to derive sheaf-theoretic constraints from the geometric vertex algebras of Joyce. Our approach applies to more general linear categories. For both sheaves and representations of quivers, I will explain that Virasoro costraints determine primary states of the vertex algebra. This is already sufficient to illustrate the formulation for any linear theory, and it leads to the proof of many results via wall-crossing.
