DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/29/
 ">Quantum cohomology of blow-ups: a conjecture</a>\nby Hiroshi Iritani (Ky
 oto) as part of Online Nottingham algebraic geometry seminar\n\n\nAbstract
 \nIn this talk\, I discuss a conjecture that a semiorthogonal decompositio
 n of topological $K$-groups (or derived categories) due to Orlov should in
 duce a relationship between quantum cohomology under blowups. The relation
 ship between quantum cohomology can be described in terms of solutions to 
 a Riemann-Hilbert problem.\n
