Quantum cohomology of blow-ups: a conjecture

Abstract: In this talk, I discuss a conjecture that a semiorthogonal decomposition of topological $K$-groups (or derived categories) due to Orlov should induce a relationship between quantum cohomology under blowups. The relationship between quantum cohomology can be described in terms of solutions to a Riemann-Hilbert problem.
