Common fixed point theorems for firmly nonspreading mappings and quasi-nonexpansive mappings in CAT(0) spaces

Common fixed point theorems for firmly nonspreading mappings and quasi-nonexpansive mappings in CAT(0) spaces

© 2020 by the Mathematical Association of Thailand. In this paper, we prove the existence of a common fixed point for firmly nonspreading mappings and quasi-nonexpansive mappings in CAT(0) spaces. Using the concept of Ishikawa iterative scheme, we define the sequence {xn} by (Formula Presented) for...
