Fixed points of periodic mappings in Hilbert spaces
Víctor García, Helga Nathansky (2010)
Annales UMCS, Mathematica
Similarity:
In this paper we give new estimates for the Lipschitz constants of n-periodic mappings in Hilbert spaces, in order to assure the existence of fixed points and retractions on the fixed point set.
