Another Generalized Nonlinear Diagonal Dominance

Another concept of generalized diagonal dominance for nonlinear functions (i.e. quasi-generalized nonlinear diagonal dominance) is introduced. This concept includes as special case generalized nonlinear diagonal dominance, possess much of important properties of generalized nonlinear diagonal dominance, easy to judge a nonlinear function is quasi-generalized nonlinear diagonally dominant if its derivative is a generalized diagonally dominant matrix on an convex set in Rn.
