  • In this paper,we define a generalized relative degree for A-proper mappings from a relative open subset of a Banach space into another Banach space and introduce the concepts of generalized P-compact and P1-compact mappings.Next,we show several existence theorems of positive solutions for the equations involving these mappings.Our theorems improve and extend some recent results.
