Hh. Bui, A HILBERT C-ASTERISK-MODULE METHOD FOR MORITA EQUIVALENCE OF TWISTED CROSSED-PRODUCTS, Proceedings of the American Mathematical Society, 125(7), 1997, pp. 2109-2113
We present a new proof for Morita equivalence of twisted crossed produ
cts by coactions within the abstract context of crossed products of Hi
lbert C-modules. In this context we are free from representing all C*
-algebras and Hilbert C-modules on Hilbert spaces.
