The object of this paper is a theoretical study of the convergence of approximation methods (Galerkin and finite difference methods) to compute eigenelements of a closed linear operator T in a Banach ...
This paper gives explicit rational functions for interpolating and approximating functions on the intervals $\lbrack-1, 1\rbrack, \lbrack0, \infty\rbrack$, and $\lbrack-\infty, \infty\rbrack$. The ...
