Abstract

We consider the system of linear functional equations ∑_(j=1)^n▒a_iJ f_i (A_iJ (x))=g_i (x),x  I  R,1  i  n (1) where I is a bounded or unbounded interval, g_i : I → R, A_iJ ∶ I → I, 1  i , j  n are the given continuous functions. We prove the existence and uniqueness of solution of the system (1) . Numerical results are given.
