On the structure of fixed-point sets of asymptotically regular semigroups
arXiv:1201.0986 · doi:10.1016/j.jmaa.2012.03.036
Abstract
We extend a few recent results of Górnicki (2011) asserting that the set of fixed points of an asymptotically regular mapping is a retract of its domain. In particular, we prove that in some cases the resulting retraction is Hölder continuous. We also characterise Bynum's coefficients and the Opial modulus in terms of nets.
