C¤-ALGEBRAS OF INTEGRAL DOMAIN

Let R be an integral domain with finite quotients and U[R] be its C¤-algebra. It is possible to show that U[R] is a partial crossed product. Also, if K is the field of fractions of R and K0 = K¡f0g, then we can show that U[R] is isomorphic to a partial group algebra of the group K £ K0
