Abstract:

We present an elementary proof that every twisted ${C^ \ast }$-dynamical system is Morita equivalent to an ordinary system. As a corollary we prove the equivalence ${C_0}(G/H,A){ \times _{\tilde \alpha ,\tilde u}}G \sim A{ \times _{\alpha ,u}}H$ for Busby-Smith twisted dynamical systems, generalizing an important result of Green.
