The convergence rate of an iterative projection method
The author considers an operator equation of the second kind in the Banach space \(E\): \[ u + Tu = f, u \in E, f \in E \] where \(T\) is a linear bounded operator on \(E\) and this equation is solved by Galerkin and finite elements methods. The order of the convergence rate is established for one variant of the Galerkin method and for an iterative finite element method for operator equations.
