The present paper is a continuation of investigations on subbase convexity theory, st arte d in [7] and in [8]. We are now concerned with so-called convexity preserving (cp) mappings, a notion comparable to affine mappings in vector space theory. A first result is a characterization of cp maps in t

In the present paper we construct q-Szász-Mirakjan operators that preserve x 2 . The rate of global convergence is obtained in the frame of weighted spaces. Furthermore, we obtain a Voronovskaja type theorem for these operators.
