On the value function for nonautonomous optimal control problems with infinite horizon
J. Baumeister, A. Leitao, G. N. Silva
In this paper we consider nonautonomous optimal control problems of infinite horizon type, whose control actions are given by -functions. We verify that the value function is…
Modified iterated Tikhonov methods for solving systems of nonlinear ill-posed equations
J. Baumeister, A. De Cezaro, A. Leitao
We investigate iterated Tikhonov methods coupled with a Kaczmarz strategy for obtaining stable solutions of nonlinear systems of ill-posed operator equations. We show that the prop…
Optimal exploitation of renewable resource stocks: Necessary conditions
J. Baumeister, A. Leitao
We study a model for the exploitation of renewable stocks developed in Clark et al. (Econometrica 47 (1979), 25-47). In this particular control problem, the control law contains a…
On iterative methods for solving ill-posed problems modeled by PDE's
J. Baumeister, A. Leitao
We investigate the iterative methods proposed by Maz'ya and Kozlov (see [KM1], [KM2]) for solving ill-posed inverse problems modeled by partial differential equations. We consider…
On Levenberg-Marquardt-Kaczmarz iterative methods for solving systems of nonlinear ill-posed equations
J. Baumeister, B. Kaltenbacher, A. Leitao
In this article a modified Levenberg-Marquardt method coupled with a Kaczmarz strategy for obtaining stable solutions of nonlinear systems of ill-posed operator equations is invest…
