Simultaneous Approximation of Function and Derivative on [0,∞] and an Application to Initial Value Problems

  • Charles Hall
Part of the NATO Advanced Study Institutes Series book series (ASIC, volume 49)


Convergence of the approximation of a class of functions defined on [0,∞] and their derivatives by exponomials and Laguerre functions is established. These results are used in the analysis of a new finite element type for initial value problems.
