Weighted Laplace Spaces for Spectral Measures and Rational Approximation

Stefan Jakobsson, Alice Kozakevicius, Stig Larsson

We introduce the weighted Laplace space $H_w$, an RKHS of Laplace transforms on $(0,\infty )$, and study spectral measures in its dual space $H_w^{\prime }$. For conforming FEM discretizatio…
