Simultaneous spatial-parametric collocation approximation for parametric PDEs with log-normal random inputs

Dinh DÅ©ng, 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…
