In this paper, we introduce a q-analogue of the Szasz-Mirakyan-Kantorovich operators and we propose two different modifications of the q-Szasz-Mirakyan-Kantorovich operators. These modifications preserve some test functions. We also examine the rate of convergence for the constructed operators by means of modulus of continuity. (C) 2011 Elsevier Ltd. All rights reserved.
