The Mathematical center in Akademgorodok invites you to take part in the
"Beijing-Novosibirsk seminar on geometry and mathematical physics" on April 14 at 4 pm Novosibirsk time (UTC+7).
The seminar's heads: A. E. Mironov, I. A. Taimanov, Huijun Fan, Youjin Zhang.
During the seminar Prof. Xiaobo Liu (Peking University, Beijing) will present his talk "Hall-Littlewood functions and Virasoro constraints".
Hall-Littlewood functions are generalizations of Schur Q-functions which have been used to study Kontsevich-Witten and Brezin-Gross-Witten tau functions. Recently Mironov and Morozov proposed to use Hall-Littlewood functions specialized at roots of unity to study generalized Kontsevich matrix models. Virasoro constraints are powerful tools in the study of matrix models and Gromov-Witten invariants. In this talk, I will describe how Virasoro operators act on Hall-Littlewood functions and applications of such formulas. This is based on joint works with Chenglang Yang.
