Abstract
It is a well-known fact that endomorphisms of are intimately connected with families of mutually orthogonal isometries, that is, with representations of the so-called Toeplitz -algebras. In this paper we consider a natural generalization of this connection between the representation theory of certain -algebras associated with graphs and endomorphisms of certain von Neumann subalgebras of . Our primary results give criteria by which it may be determined if two representations give rise to equal or conjugate endomorphisms.
