报告摘要：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). Key topics will include their coideal structure and shifted generalizations.
