Laguerre- and Laplace-weighted integration of mixed-smoothness functions
Dinh Dũng
We investigate the approximation of generalized Laguerre- or Laplace-weighted integrals over or of functions from generalized Laguerre- or Laplace-w…

Simultaneous spatial-parametric collocation approximation for parametric PDEs with log-normal random inputs
Dinh Dũng
We establish convergence rates for a fully discrete, multi-level, linear collocation method solving parametric elliptic PDEs on bounded polygonal domains with log-normal inputs. Th…
