In the present paper, we deal with the approximation properties of semi-exponential Szász-Mirakyan-Kantorovich operators. Here, we establish the relation between semi-exponential Szász-Mirakyan-operators and its Kantorovich variant. Further, we propose the modification of the Kantorovich variant so as to preserve the test functions e Ax and e 2Ax and we derive the Voronovskaya-type result.
