A parallel-in-time preconditioner for Crank-Nicolson discretization of a parabolic optimal control problem

Xue-Lei Lin, Shu-Lin Wu

In this paper, a fast solver is studied for saddle point system arising from a second-order Crank-Nicolson discretization of an initial-valued parabolic PDE constrained optimal con…
