Let E be a reflexive real Banach space with uniformly Gâteaux differentiable norm and F, K : 𝐸 β†’ 𝐸 be Lipschitz accretive maps with 𝐷 ( 𝐾 ) = 𝑅 ( 𝐹 ) = 𝐸 . Suppose that the Hammerstein equation 𝑒 + 𝐾 𝐹 𝑒 = 0 has a solution. An explicit iteration method is shown to converge strongly to a solution of the equation. No invertibility assumption is imposed on K and the operator F is not restricted to be angle-bounded. Our theorems are significant improvements on important recent results (e.g., (Chiume and Djitte, 2012)).
