Approximation by Complex $$q$$ -Szász–Kantorovich Operators in Compact Disks, $$q>1$$

APPROXIMATION BY GENERALIZED q-SZASZ-MIRAKJAN ´ OPERATORS

“…In recent times, the q−calculus has been extensively used in approximation theory (e.g. Aral [3], Aral and Gupta [4], Gal et al [6], Mahmudov [12], Ostrovska [20], Rao et al [23], Singh and Gairola [24] etc.). Using q−calculus, more suitable and useful generalizations of many classical operators have been obtained and investigated.…”

Approximation by (p, q)-Lorentz Polynomials on a Compact Disk

“…Details on the q-calculus can be found in [1,15] Several authors have introduced and studied the approximation properties for different operators in compact disk. For instance, in [8,9,10] Mahmudov studied q-Stancu polynomials, q-Szasz Mirakjan operators and generalised Kantorovich operators; In [2] Gal et al studied q-szasz-Kantorovich operators.…”
