Supremum-norm a posteriori error control of quadratic discontinuous Galerkin methods for the obstacle problem

Rohit Khandelwal, Kamana Porwal, Ritesh Singla

We perform a posteriori error analysis in the supremum norm for the quadratic discontinuous Galerkin method for the elliptic obstacle problem. We define two discrete sets (motivate…

Adaptive quadratic finite element method for the unilateral contact problem

Rohit Khandelwal, Kamana Porwal, Tanvi Wadhawan

In this paper, we present and analyze a posteriori error estimates in the energy norm of a quadratic finite element method for the frictionless unilateral contact problem. The reli…
