Speaker: Razieh Ahmadian, Shahid Beheshti University (Iran)
Title: TBA
Abstract: TBA
Date: May 1, 2024
Time: 17:30-19:00 Tehran time


Speaker: Rita Pardini, University of Pisa (Italy)
Title: Exploring the boundary of the moduli space of stable surfaces: some explicit examples
Abstract: I will briefly recall the notion of stable surfaces and of the corresponding moduli space. Then I will outline a partial description of the boundary points in the case of surfaces with $K^2=1$, $p_g=2$ (joint work with Stephen Coughlan, Marco Franciosi, Julie Rana and Soenke Rollenske, in various combinations) and, time permitting, in the case of Campedelli and Burniat surfaces (joint work with Valery Alexeev).
Date: May 15, 2024
Time: 17:30-19:00 Tehran time


Speaker: Jonas Stelzig, LMU Munich (Germany)
Title: Linear combinations of cohomological invariants of compact complex manifolds
Abstract: In the 50s, Hirzebruch asked which linear combinations of Hodge and Chern numbers are topological invariants of compact complex manifolds. Building on ideas of Schreieder and Kotschick, who solved the Kähler case, I will present a general answer to this question (and some related ones). Furthermore, I will outline a program how to tackle similar questions when incorporating more cohomological invariants, eg the dimensions of the Bott Chern cohomology groups. This will naturally lead to an algebraic study of the structure of bicomplexes, as well as a number of challenging geometric construction problems.
Date: May 29, 2024
