Lokesha c Communicated by W. Sprößig The aim of this paper was to derive new identities and relations associated with the q-Bernstein polynomials, q-Frobenius– Euler polynomials, l-functions, and q-Stirling numbers of the second kind. We also give some applications related to theses polynomials and numbers. Copyright © 2012 John Wiley & Sons, Ltd. Keywords: q-Bernstein polynomials; q-Frobenius–Euler polynomials; l-functions; q-Stirling numbers of the second kind 1. Introduction Throughout this paper, we make use of the following notations: C denotes the set of complex numbers and N 0 D N[f0g , N Df1, 2, 3, g denotes the set of non-negative integers. For q 2 C (jqj < 1), the q-number Œa, qand the q-number factorial Œa, qŠ are defined by (see, for details, [1]) Œ0, qD 0, and Œa, qD 1 q a 1 q , where q ¤ 1; a 2 C, Œ0, qŠ D 1 and Œk, qŠ D Œ1, qŠ Œ2, qŠ Œ3, qŠ  Œk, qŠ, where k 2 N, respectively. One has the following limit cases: lim q!1 Œa, qD a and lim q!1 Œn, qŠ D nŠ cf. [2–16].
