✦ Synopsis
We study the BKP hierarchy and its n-reduction, for the case that n is odd. This is related .~(2) to the principal realization of the basic module of the twisted affine Lie algebra Sl~ . We show that the following two statements for a BKP ~-function are equivalent: (1) 7 is is n-reduced and satisfies the string equation, i.e., L_~T = 0, where L-l is an element of some 'natural' Virasoro algebra. (2) ~-satisfies the vacuum constraints of the BWI+~ algebra. Here BW~+~ is the natural analog of the W~+~ algebra, which plays a role in the KP case.
