Abstract

In 1999 Chas and Sullivan showed that the homology of the free loop space of an oriented manifold admits the structure of a Batalin–Vilkovisky algebra. In this paper we give a direct description of this Batalin–Vilkovisky algebra in the case where the manifold is a compact Lie group G. Our answer is phrased in terms of the homology of G, the homology of the space of based loops on G, and the homology suspension. The result is applied to compute the Batalin–Vilkovisky algebra associated to the special orthogonal groups SO(n) with coefficients in the rational numbers and in the integers mod 2.
