摘要
In this paper we consider a C*-subalgebra of the algebra of all bounded operators B(l(2)(X)) on theHilbert space l(2)(X) with one generating element T-phi induced by a mapping phi of a set X into itself. We prove that such a C*-algebra has an AF-subalgebra and establish commutativity conditions for the latter. We prove that a C*-algebra generated by a mapping produces a dynamic system such that the corresponding group of automorphisms is invariant on elements of the AF-subalgebra.
