Condensing mappings and applications to existence theorems for common solution of differential equations. (English) Zbl 0940.47043

Summary: Some common fixed point theorems for pairs of condensing mappings in a Banach space are proved and applications are given to a pair of nonlinear first-order ordinary differential equations in Banach spaces for proving the existence of common solution under suitable conditions.
