Tytuł:: Gradient method for non-injective operators in Hilbert space with application to Neumann problems
Autorzy:: Karátson, János
Powiązania:: https://bibliotekanauki.pl/articles/1338793.pdf
Data publikacji:: 1999
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: Neumann boundary value problems
non-injective non-linear operator
gradient method
Hilbert space
Opis:: The gradient method is developed for non-injective non-linear operators in Hilbert space that satisfy a translation invariance condition. The focus is on a class of non-differentiable operators. Linear convergence in norm is obtained. The method can be applied to quasilinear elliptic boundary value problems with Neumann boundary conditions.

Tytuł:: Quasilinear vector differential equations with maximal monotone terms and nonlinear boundary conditions
Autorzy:: Bader, Ralf
Papageorgiou, Nikolaos
Powiązania:: https://bibliotekanauki.pl/articles/1208032.pdf
Data publikacji:: 2000
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: Dirichlet
maximal monotone operator

coercive operator
projection theorem
Opis:: We consider a quasilinear vector differential equation which involves the p-Laplacian and a maximal monotone map. The boundary conditions are nonlinear and are determined by a generally multivalued, maximal monotone map. We prove two existence theorems. The first assumes that the maximal monotone map involved is everywhere defined and in the second we drop this requirement at the expense of strengthening the growth hypothesis on the vector field. The proofs are based on the theory of operators of monotone type and on the Leray-Schauder fixed point theorem. At the end we present some special cases (including the classical Dirichlet, Neumann and periodic problems), which illustrate the general and unifying features of our work.

Tytuł:: Optimal control problem for infinite variables hyperbolic systems with time lags
Autorzy:: Bahaa, G. M.
Tharwat, M. M.
Powiązania:: https://bibliotekanauki.pl/articles/229952.pdf
Data publikacji:: 2011
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: optimal control
hyperbolic system
time delay
distributed control problems
Neumann conditions
existence and uniqueness of solutions
second order operator with an infinite number of variables
Opis:: In this paper, by using the theorems of [Lions (1971) and Lions & Magenes (1972)], the optimal control problem for distributed hyperbolic systems, involving second order operator with an infinite number of variables, in which constant lags appear both in the state equations and in the boundary conditions is considered. The optimality conditions for Neumann boundary conditions are obtained and the set of inequalities that characterize these conditions is formulated. Also, several mathematical examples for derived optimality conditions are presented. Finally, we consider an optimal distributed control problem for (n x n)-infinite variables hyperbolic systems.
