SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Stability and Moduli on Kuznetsov Components of Cubic 5-Folds
DESCRIPTION:Bridgeland stability is notoriously hard to construct on varieties of dimension > 2. One promising workaround is to focus on the Kuznetsov component of Fano varieties — a residual piece of the derived category that often captures the essential geometric information. In this talk\, I will explain the construction of stability conditions on Kuznetsov components using the machinery of quadric fibrations introduced by Bayer–Lahoz–Macrì–Stellari. I will illustrate how this technique applies to cubic 5-folds as a new higher-dimensional example. In the second part\, I will then describe properties of the associated moduli spaces. In particular\, they admit immersions into hyper-Kähler varieties with Lagrangian image\, generalizing a geometric construction of Illiev–Manivel.

SUMMARY:Workshop / Seminar:Macroscopic market making
DESCRIPTION:Trade execution and market making are two central problems in algorithmic trading that have largely been studied in separate literatures. In this talk\, I present a unified approach that addresses both problems simultaneously in three steps.\n\nWe introduce a macroscopic market making model à la Avellaneda-Stoikov\, using continuous processes for orders instead of discrete point processes. Since the impact of a single market maker on price is typically negligible\, we then develop the corresponding game formulation. Finally\, we can connect traders with market makers.\n  \nSubsequently\, we present our mathematical contributions. The goal is to derive the global well‑posedness of the optimal control/Nash equilibrium. The discussion addresses topics in game theory\, non‑smooth analysis\, FBSDEs\, and Riccati equations.\n\nReferences:\nIvan Guo\, Shijia Jin\, and Kihun Nam\, Macroscopic Market Making.
