Special family of non-bijective multivariate maps \(F_n\) of \({Z_m}^n\)into itself is constructed for \(n = 2, 3, \dots\) and composite~\(m\).The map \(F_n\) is injective on \(\Omega_n=\{{\rm x}|x_1+x_2 + \dotsx_n \in {Z_m}^* \}\) and solution of the equation \(F_n({\rm x})={\rmb}, {\rm x}\in \Omeg...
