Abstract

We continue our discussion of the general bosonic prototype of the new orbifold-string theories of permutation type. Supplementing the extended physical-state conditions of the previous paper, we construct here the extended Virasoro generators with cycle central charge , where is the length of cycle in twisted sector . We also find an equivalent, reduced formulation of each physical-state problem at reduced cycle central charge . These tools are used to begin the study of the target space-time dimension of cycle in sector , which is naturally defined as the number of zero modes (momenta) of each cycle. The general model-dependent formulae derived here will be used extensively in succeeding papers, but are evaluated in this paper only for the simplest case of the "pure" permutation orbifolds.
