1. Introduction
Recently, many mathematicians have studied in the area of the Euler numbers and polynomials (see [1–15]). The Euler numbers and polynomials possess many interesting properties and arising in many areas of mathematics and physics. In [14], we introduced that Euler equation has symmetrical roots for (see [14]). It is the aim of this paper to observe an interesting phenomenon of “scattering” of the zeros of the generalized Euler polynomials in complex plane. Throughout this paper, we use the following notations. By , we denote the ring of adic rational integers, denotes the field of adic rational numbers, denotes the completion of algebraic closure of , denotes the set of natural numbers, denotes the ring of rational integers, denotes the field of rational numbers, denotes the set of complex numbers, and .
