Abstract: The main purpose of this paper is to introduce a new algorithm for finding a solution of split equality variational inequality problem for monotone and Lipschitz continuous operators and common fixed points of a finite family of quasi-nonexpansive mappings in the setting of infinite dimensional Hilbert spaces. Under suitable conditions, we prove that the sequence generated by the proposed new algorithm converges strongly to a solution of the split equality variational inequality and fixed point problem in Hilbert spaces. Our results improve and generalize some recent results in the literature.
