Convergence Analysis Of Pseudo-Transient Continuation

open access: yes, 1997
. Pseudo-transient continuation (\Psitc) is a well-known and physically motivated technique for computation of steady-state solutions of time-dependent partial differential equations.

A Fast Multilevel Algorithm For Integral Equations

open access: yes, 1993
. We show how the discretization of integral equations by composite Gauss rules can be related to approximations of integral operators that converge in the operator norm, rather than strongly. From this norm convergent formulation a two level approximate

A Trust Region Method For Parabolic Boundary Control Problems

open access: yes, 2007
. In this paper we develop a trust region algorithm for constrained parabolic boundary control problems. The method is a projected form of the Steihaug trust-region-CG method with a smoothing step added at each iteration to improve performance in the ...

A Fast Multilevel Algorithm For The Solution Of Nonlinear Systems Of Conductive-Radiative Heat Transfer Equations In Two Space Dimensions

open access: yes, 1997
. In this paper we describe a fast multilevel algorithm for the solution of a system of nonlinear integrodifferential equations that model steady-state combined conductive-radiative heat transfer in two space dimensions. This extends our previous work in

Mesh Independence Of Matrix-Free Methods For Path Following

open access: yes, 1999
. In this paper we consider a matrix-free path following algorithm for nonlinear parameter-dependent compact fixed point problems. We show that if these problems are discretized so that certain collective compactness and strong convergence properties ...

Solution Of Optimal Control Problems By A Pointwise Projected Newton Method

open access: yes, 1995
. In the context of optimal control of ordinary differential equations, we prove local superlinear convergence and constraint identification results for an extension of the projected Newton method of Bertsekas.
