Singular Contractions of W-algebras

High Energy Physics - Theory 2015-06-26 v1

Abstract

Many WW-algebras (e.g. the WNW_N algebras) are consistent for all values of the central charge except for a discrete set of exceptional values. We show that such algebras can be contracted to new consistent degenerate algebras at these exceptional values of the central charge.
