Error analysis for parabolic optimal control problems with measure data in a nonconvex polygonal domain
Pratibha Shakya
This paper considers the finite element approximation to parabolic optimal control problems with measure data in a nonconvex polygonal domain. Such problems usually possess low reg…

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…
