Abstract: The purpose of this article is to modify the Halpern-type iteration algorithm for total quasi-ϕ-asymptotically nonexpansive mapping to have the strong convergence under a limit condition only in the framework of Banach spaces. The results presented in the paper improve and extend the corresponding results of [X.L. Qin, Y.J. Cho, S.M. Kang, H. Y. Zhou, Convergence of a modified Halpern-type iterative algorithm for quasi-ϕ-nonexpansive mappings, Appl. Math. Lett. 22 (2009) 1051–1055], [Z.M. Wang, Y.F. Su, D.X. Wang, Y.C.

Abstract: The purpose of this paper is to introduce and study a class of more general multivalued quasi-variational inclusions in Banach spaces. By using the accretive operator technique, we establish the equivalence between these kinds of multivalued quasi-variational inclusions and a kind of multivalued accretive equations in Banach space. Then, invoking Michael''s selection theorem and Nadler''s theorem, some existence theorems and iterative algorithms for solving this kind of multivalued quasi-variational inclusions in Banach spaces are established and suggested.
