报告摘要:As a generalization of Yangians introduced by Drinfeld in 1986, twisted Yangians are deformation of twisted current algebras. In recent joint work with Kang Lu and Weinan Zhang, we have obtained Drinfeld type current presentations of twisted Yangians of type AI and beyond through Gauss decomposition and degeneration. Further parabolic and shifted generalization of these presentations in type AI and AII have led to connections to finite W-algebras of type BCD, in joint work with Lu, Peng, Tappeiner and Topley. In this talk, we will explain some of these works.
