The General Twisted Open WZW String
Abstract
We recently studied two large but disjoint classes of twisted open WZW strings: the openstring sectors of the WZW orientation orbifolds and the socalled basic class of twisted open WZW strings. In this paper, we discuss all Tdualizations of the basic class to construct the general twisted open WZW string — which includes the disjoint classes above as special cases. For the general case, we give the branes and twisted noncommutative geometry at the classical level and the twisted openstring KZ equations at the operator level. Many examples of the general construction are discussed, including in particular the simple case of twisted freebosonic open strings. We also revisit the openstring sectors of the general WZW orientation orbifold in further detail. For completeness, we finally review the general twisted boundary state equation which provides a complementary description of the general twisted open WZW string.
