Abstract
We demonstrate that the Kac-Moody and Virasoro-like algebras on Riemann surfaces of arbitrary genus with two punctures introduced by Krichever and Novikov are in two ways linearly related to Kac-Moody and Virasoro algebras onS 1. The two relations differ by a Bogoliubov transformation, and we discuss the connection with the operator formalism.
