In this paper, we present a generalization of the classical Korovkin theorem on positive linear operators. We deduce some convergence results for linear operators defined on C k [0, 1], that preserve some cones of functions related to shape properties. Finally, we show some examples.

Let A be a separable exact quasidiagonal C\*-algebra. Suppose that ?: A Ä L(H) is a faithful representation whose image does not contain nonzero compact operators. Then there exists a sequence . n : A Ä L(H) of completely positive contractions such that &?(a)&. n (a)& Ä 0 for all a # A, and the C\*-
