In this paper, we discuss the Valiron’s theorem in the unit polydisk DN. We prove that for a holomorphic map φ : DN→ DNsatisfying some regular conditions, th
In this paper we study the solutions and stability of the generalized Wilson’s functional equation ∫_Gf(xty)dμ(t) + ∫_Gf(xtσ(y))dμ(t) = 2f(x)g(y),x,y ∈ G
