Weak Ergodic Theorem for General Semigroups in Banach Spaces
Jianmei Zhang · 2009
This paper studies the problem of weak ergodic theorem for asymptotically non- expansive type mappings of general semigroups in real reflexive Banach spaces with Frechet differential norm by a new method. Furthermore , we obtain the weak ergodic theorem for the almost orbits of asymptotically nonexpansive type semigroups without almost asymptotically isometric.
