摘要：
In this paper, using a class of semigroups of not necessarily continuous mappings in a Banach space which includes discrete semigroups of generalized nonspreading mappings and semigroups of phi-nonexpansive mappings, we establish a strong convergence theorem of Halpern's type iteration for the semigroups of mappings in a Banach space. Using the result, we obtain well-known and new theorems which are connected with strong convergence results in Hilbert spaces and Banach spaces. It seems that such a strong convergence theorem is first for classes of semigroups of not necessarily continuous mappings in a Banach space.
