Summary:
We
prove a conjecture of Lian and Zuckerman, that the natural Gerstenhaber
algebra structure present in the cohomology of a vertex algebra may be
lifted (modulo some technical conditions) to a
strong-homotopy-Gerstenhaber structure on the vertex algebra itself.
This is joint work with V Gorbounov and A Tonks.
