Central extensions and semi-infinite wedge representations of Krichever-Novikov algebras for more than two points

By Martin Schlichenmaier

Abstract

For the generalized Krichever-Novikov algebras of meromorphic vector fields and their induced modules of weight λ a different basis is given. With respect to this basis the module structure is generalized graded. "Local" central extensions of these algebras and their representations on the space of semi-infinite wedge product of forms of weight λ are studied. In this generalization one obtains again
