Abstract: The main purpose of this paper is to analyze the convergence and regularity of the proposed algorithm (J. Nonlinear Sci. Appl. 9 (2016), 568–583) of the discontinuous Galerkin methods coupled with Euler time discretization scheme for parabolic quasi-variational inequalities with nonlinear source terms and an obstacle defined as impulse control problem.
