In this paper. we introduce a triple Mann iteration method for approximating an element in the set of common solutions of a system of quasivariational inclusion issues. which is an equilibrium problem and a common fixed point problem (CFPP) of finitely many quasi-nonexpansive operators on a Hadamard manifold. Through some suitable assumptions. https://miamistares.shop/product-category/clearance-marker-and-s-t-t/
