Maeda, Yoshiaki (ed.) et al., Symplectic geometry and quantization. Papers presented at the 31st Taniguchi international symposium on symplectic geometry and quantization problems held at Sanda, Japan, July 12-17, 1993 and a satellite symposium held at Keio University, Yokohama, Japan, from July 21-24, 1993. Providence, RI: American Mathematical Society. Contemp. Math. 179, 173-192 (1994).
The author’s abstract: Drinfeld has given an idea of multiplicative Poisson structures on Lie groups. The essential derivative of a multiplicative Poisson structure at the unit element of a group defines a Lie algebra structure on the dual space of the Lie algebra of the group. It is known that classical \(r\)-matrices give multiplicative Poisson structures. In this paper we find classical \(r\)-matrices of some loop groups and study dual Lie algebra structures defined by them”.
