## On the iterative methods with high convergence orders

Abstract Let $$X$$ be a Banach space and $$Y$$ a normed space, and $$P:X\rightarrow Y$$ a nonlinear operator. In order…

## Interpolation in linear normed spaces and applications

Abstract Let $$X,Y$$ be two normed spaces and $$P:X\rightarrow Y$$ a nonlinear operator. We construct the Lagrange interpolation operator for…
