Moduli and Algebraic Cycles

May 29 - June 2, 2023

This workshop is a follow-up to the research program Moduli and Algebraic Cycles which took place during the fall of 2021. In the workshop we aim to continue exploring the themes and questions related to that programme, and to bring together leading researchers in algebraic geometry. We expect that some of the key topics in the workshop will be related to Hodge theory and period domains, intersection theory on moduli stacks, the geometry of stability conditions for moduli of sheaves, logarithmic geometry, rationality problems, Griffiths groups, and Hyperkähler manifolds.
