Abstract: | Let be a domain with smooth boundary and let α be a C
2-
diffeomorphism on satisfying the Carleman condition .We denote
by the C*-algebra generated by the Bergman projection of G, all multiplication
operators aI and the operator where is the Jacobian of α. A symbol algebra of is determined and Fredholm
conditions are given. We prove that the C*-algebra generated by the Bergman
projection of the upper half-plane and the operator is isomorphic
and isometric to .
