DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CGP-MP/29/">
 Hall-Littlewood functions and Virasoro constraints</a>\nby Xiaobo Liu (Bei
 jing International Center for Mathematical Research) as part of IBS-CGP Ma
 thematical Physics Seminar\n\n\nAbstract\nHall-Littlewood functions are ge
 neralizations of Schur Q-functions which have been used to study Kontsevic
 h-Witten and Brezin-Gross-Witten tau functions. Recently Mironov and Moroz
 ov proposed to use Hall-Littlewood functions specialized at roots of unity
  to study generalized Kontsevich matrix models. Virasoro constraints are p
 owerful tools in the study of matrix models and Gromov-Witten invariants. 
 In this talk\, I will describe how Virasoro operators act on Hall-Littlewo
 od functions and applications of such formulas. This is based on joint wor
 ks with Chenglang Yang.\n
