A perturbed preconditioned gradient descent method for the unconstrained minimization of composite objectives

Jea-Hyun Park, Abner J. Salgado, Steven M. Wise

We introduce a perturbed preconditioned gradient descent (PPGD) method for the unconstrained minimization of a strongly convex objective $G$ with a locally Lipschitz continuous gra…

Finite element approximation to linear, second order, parabolic problems with $L^{1}$ data

Gabriel Barrenechea, Abner J. Salgado

We consider the approximation to the solution of the initial boundary value problem for the heat equation with right hand side and initial condition that merely belong to $L^{1}$ . Du…
