摘要：

The existence of common fixed points is established for the mappings, where T is (f, theta, L)-weak contraction on a nonempty subset of a Banach space. As application, some results on the invariant best approximation are proved. Our results unify and substantially improve several recent results given by some authors. Copyright (C) 2009 N.
