Convergence of an adaptive mixed finite element method for general second order linear elliptic problems
Asha K. Dond, Neela Nataraj, Amiya K. Pani
The convergence of an adaptive mixed finite element method for general second order linear elliptic problems defined on simply connected bounded polygonal domains is analyzed in th…

Error analysis of nonconforming and mixed FEMs for second-order linear non-selfadjoint and indefinite elliptic problems
Carsten Carstensen, Asha K. Dond, Neela Nataraj +1
The state-of-the art proof of a global inf-sup condition on mixed finite element schemes does not allow for an analysis of truly indefinite, second-order linear elliptic PDEs. This…
