Horiguchi, Tsutomu; Sakamoto, Makoto; Tabuse, Masayoshi Cocycle properties of string theories on orbifolds. (English) Zbl 0839.58074 Kato, Mitsuhiro (ed.) et al., Recent developments in string and field theory. Kyoto: Yukawa Institute for Theoretical Physics and The Physical Society of Japan, Prog. Theor. Phys., Suppl. 110, 229-259 (1992). Summary: We study cocycle properties of vertex operators and present an operator representation of cocycle operators, which are attached to vertex operators to ensure the duality of amplitudes. It is shown that this analysis makes it possible to obtain the general class of consistent string theories on orbifolds.For the entire collection see [Zbl 0822.00016].
