A Multilevel Stochastic Collocation Method for Partial Differential Equations with Random Input Data
Aretha L. Teckentrup, Peter Jantsch, Clayton G. Webster +1
Stochastic collocation methods for approximating the solution of partial differential equations with random input data (e.g., coefficients and forcing terms) suffer from the curse…
