Abstract

Let X be compact Hausdorff, and ϕ: X → X a continuous surjection. Let A be the semicrossed product algebra corresponding to the relation fU = Uf∘ ϕ. Then the C^*-envelope of A is the crossed product of a commutative C^*-algebra which contains C(X) as a subalgebra, with respect to a homeomorphism which we construct. We also show there are``sufficiently many'' nest representations.
