An efficient and reliable a-posteriori error estimator is developed for a characteristic-Galerkin FEM for time-dependent convection-dominated problems.
The discontinuous Galerkin(DG)method is known to provide high resolution properties,especially when applying after long time run.In this talk,we consider an
We present an algorithm based on the active set strategy to simulate crack propagation using a quasi-static fracture model.The crack is discretized using a
This talk is on implementing the Multivariate Decomposition Method(MDM)for approximating integrals over the infinite-dimensional unit cube,see "The multivar
QPT(quasi-polynomial tractability)is well understood for for linear multivariate problems in various settings when linear information is used.We present cur
We compare the average errors of linear and non-linear approximations assuming that the coefficients in an orthogonal expansion are scaled i.i.d.random vari
Numerical methods for high dimensional integration and approximation play a crucial role in a number of applications.This session brings together experts fr
In this talk,we will review several recent result in PDE constrained optimization with pointwise constraints on the gradient of the state.This includes barr
