Abstract

In this paper, we study the virtual element discretization of an elliptic optimal control problem with pointwise Neumann boundary control constraint. We construct a virtual element discrete scheme using virtual element discretzation of the state equation and variational discretization of the control variable. A priori error estimates for the state, adjoint state and control variable with respect to \(H^1\) and \(L^2\) norm are derived. Finally, numerical examples are presented to verify the theoretical findings.
