Div First-Order System LL* (FOSLL*) for Second-Order Elliptic Partial Differential Equations

Zhiqiang Cai, Rob Falgout, Shun Zhang

The first-order system LL* (FOSLL*) approach for general second-order elliptic partial differential equations was proposed and analyzed in [10], in order to retain the full efficie…

Recovery-Based Error Estimators for Diffusion Problems: Explicit Formulas

Zhiqiang Cai, Shun Zhang

We introduced and analyzed robust recovery-based a posteriori error estimators for various lower order finite element approximations to interface problems in [9, 10], where the rec…
