报告摘要：It has been an open problem since the pioneering work of Drinfeld to construct an explicit isomorphism between the R-matrix presentation and the "new realization" of the Yangian in types B, C and D. We give a solution which is based on the Gauss decomposition of the generator matrix in the R-matrix presentation. The proof relies on an embedding theorem which allows one to consider the Yangian of rank n−1 as a subalgebra of the Yangian of rank n of the same type. This is joint work with Naihuan Jing and Ming Liu
