Hurwitz numbers, matrix models, commuting operators, А.Ю. Орлов

Докладчик: А.Ю. Орлов Тема: Hurwitz numbers, matrix models, commuting operators Аннотация: We will analyze how matrix models are related to arbitrary Hurwitz numbers. There are equivalent descriptions using (a) differential operators (b) oscillatory algebra and bosonic Fock space. Commuting sets of such operators will be presented. This is a modification of Calogero's quantum Hamiltonians at a special point. Семинар Когомологические аспекты геометрии дифференциальных уравнений А.М.Вербовецкий, И.С.Красильщик
