  • Let E be an arbitrary real Banach space and K be a nonempty closed convex subsets of E.Let T:K→K be a uniformly continuous φ-hemicontractive operator with bounded range and {an},{bn},{cn},{a'n},{b'n},{c'n}be sequences in[0,1] satisfying:ⅰ)an+bn+cn=a'n+b'n+c'n=1,∀n≥0; For any given x0,u0,v0∈K,define the Ishikawa type iterative sequence {xn} as follows: where {un} and {vn} are bounded sequences in K.Then {xn} converges strongly to the unique fixed point of T.Related result deals with the convergence of Ishikawa type iterative sequence to the solution of φ-strongly accretive operator equations.
