Primal-dual hybrid gradient (PDHG) is a first-order method for saddle-point problems and convex programming introduced by Chambolle and Pock. Recently, Applegate et al.\ analyzed the behavior of PDHG ...

Abstract: We present a closed-form solution for the electromagnetic wave equation that governs propagation in a spatially unbounded, linear time-varying gaseous plasma. Using a proper change of ...
