In this talk, I will discuss the Drinfeld’s new presentation for (Olshanski’s) twisted Yangians of type AI that is open for 30 years. This presentation comes from the Gauss decomposition and turns out to be compatible with the one obtained from degeneration of affine iQuantum Groups. If time permits, I will also discuss our work on twisted Yangians of other types.
This is a joint work with Weiqiang Wang and Weinan Zhang.
This video was part of the Southeastern Lie Theory Workshop XIII.
