Published: 2 December 2009Abstract
We give fixed point results for classes of mappings that generalize pointwise contractions,
asymptotic contractions, asymptotic pointwise contractions, and nonexpansive and asymptotic
nonexpansive mappings. We consider the case of metric spaces and, in particular, CAT
spaces. We also study the well-posedness of these fixed point problems.
