A nonconforming finite element method for an elliptic optimal control problem with constraint on the gradient
Kamana Porwal, Pratibha Shakya
This article is concerned with the nonconforming finite element method for distributed elliptic optimal control problems with pointwise constraints on the control and gradient of t…
Pointwise A Posteriori Error Analysis of a Discontinuous Galerkin Method for the Elliptic Obstacle Problem
Blanca Ayuso de Dios, Thirupathi Gudi, Kamana Porwal
We present a posteriori error analysis in the supremum norm for the symmetric interior penalty discontinuous Galerkin method for the elliptic obstacle problem. We construct discret…
Adaptive finite element method for an elliptic optimal control problem with integral state constraints
Kamana Porwal, Pratibha Shakya
In this article, we develop a posteriori error analysis of a nonconforming finite element method for a linear quadratic elliptic distributed optimal control problem with two differ…
Unified Analysis of Discontinuous Galerkin Methods for Frictional Contact Problem with normal compliance
Kamana Porwal, Tanvi
