Abstract:In recent joint work with Weiqiang Wang and Weinan Zhang, we established Drinfeld-type current presentations for twisted Yangians of type AI and beyond. These presentations are realized via Gauss decomposition and the degeneration of affine iquantum groups. In this talk, I will discuss recent progress in the study of these twisted Yangians (also known as iYangians) and explore their applications. Key topics will include their coideal structure, shifted generalizations, and connections to finite W-algebras of classical types, as well as affine Grassmannian islices (time permitting). This talk is based on joint works with Yung-Ning Peng, Lukas Tappeiner, Lewis Topley, Weiqiang Wang, Alex Weekes, and Weinan Zhang.
