For A homogenous system x(n+1)=Ax(n) of difference equations, we define P-semi-homogenous of order and adjoint. This definition is generalized to (2x2)-semi-homogeneous system of difference equations of order, where is a positive integer number. We study all special cases of this definition and give some examples. Also, we give some characterizations of those definitions, the necessary and sufficient conditions for a homogenous system of difference Equations to be P-semi homogenous of order one or greater than one is given in theorems, as well as some examples and theorems. }, number={1}, journal={Al-Mustansiriyah Journal of Science}, author={Hussein, Abdul Samad Ibrahim and Al-Asadi, Bassam Jabbar}, year={2023}, month={Mar.}, pages={71–76} }
