　　摘要：R-matrices are the solutions of the Yang-Baxter equation. The R-matrix

　　realization is an important realization of quantum algebra, which originated from the

　　study of quantum inverse scattering theory. In this talk, we will introduce our recent

　　work on R-matrix realization of quantum algebra: (1) The isomorphism between

　　R-matrix presentation and Drinfeld’s new realization of BCD type Yangians and

　　quantum affine algebras. This is a joint work with Naihuan Jing and Alexander Molev.

　　(2) The parabolic presentation of BCD type Yangian which is a joint work with

　　Zhihua Chang, Naihuan Jing and Haitao Ma.
