Research Abstract

In these four years, we have obtained several results in fixed point theory. For example, we have obtained the best possible condition on some type of Browder's convergence for nonexpansive semigroups in Hilbert spaces. We have discussed the concept of generalized nonexpansive mappings in Banach spaces and successive approximation converging to a fixed point in complete metric spaces.
