Common fixed point results for some new classes of nonlinear noncommuting maps on a locally convex space are proved. As applications, related invariant approximation results are obtained. Our work includes improvements and extension of several recent
developments of the existing literature on common fixed points. We also provide
illustrative examples to demonstrate the generality of our results over the known ones.
