Can I read An accurate flux reconstruction for discontinuous Galerkin approximations of elliptic problems on EtoBox?
An accurate flux reconstruction for discontinuous Galerkin approximations of elliptic problems by Alexandre Ern; Serge Nicaise; Martin Vohralík is a Mathematics article available to read on EtoBox.
What is An accurate flux reconstruction for discontinuous Galerkin approximations of elliptic problems about?
We introduce a new H(div) flux reconstruction for discontinuous Galerkin approximations of elliptic problems. The reconstructed flux is computed elementwise and its divergence equals the L 2 -orthogonal projection of the source term onto the discrete space. Moreover, the energy-norm of the error in the flux is bounded by the discrete energy-norm of the error in the primal variable, independently of diffusion heterogeneities.
Who reads An accurate flux reconstruction for discontinuous Galerkin approximations of elliptic problems?
It is typically read by researchers, students, and practitioners in Mathematics.
