ORIGINAL_ARTICLE Comments on relaxed $(\gamma, r)$-cocoercive mappings We show that the variational inequality $VI(C,A)$ has aunique solution for a relaxed $(gamma , r)$-cocoercive,$mu$-Lipschitzian mapping $A: Cto H$ with $r>gamma mu^2$, where$C$ is a nonempty closed convex subset of a Hilbert space $H$. Fromthis result, it can be derived that, for example, the recentalgorithms given in the references of this paper, despite theirbecoming more complicated, are not general as they should be. https://ijnaa.semnan.ac.ir/article_68_35bfd7b5fbb5e640ce2b05e93c804d24.pdf 2010-01-01T11:23:20 2020-01-24T11:23:20 54 57 10.22075/ijnaa.2010.68 Common element Contraction Fixed point Iteration Nonexpansive mapping Relaxed $(gamma , r)$-cocoercive mappings variational inequality S.
