Iterative methods for solving linear operator equations in Banach spaces

Abstract: Iterative methods for solving the linear operator equation $Ax=y$ with $B$-symmetric $B$-positive operator acting from a Banach space $X$ to a Banach space $Y$ are considered. The space $X$ is assumed to be uniformly convex and smooth, whereas $Y$ is an arbitrary Banach space. The cases of exact and disturbed data are considered and the strong (norm) convergence of the iterative processes is proved.

Keywords: iterative method, duality mapping, $B$-symmetric operator, $B$-positive operator, minimum-norm solution, Bregman distance, uniformly convex space, smooth space, Xu–Roach characteristic inequality, modulus of smoothness of a space.
