Approximation of extremal solution of non-Fourier moment problem and optimal control for non-homogeneous vibrating systems

Journal of Mathematical Analysis and Applications, 2012
Trigonometric non-Fourier moment problems arise as a result of various control problem study. In current paper, the extremal solution, i.e. the one with the least L2-norm is searched for.

Solution of an Extremal Problem

Theory of Probability & Its Applications, 1957
Let N be a set of pairs of integers $\langle {i,j} \rangle ,i, j = 1,2, \cdots ,h$, and M a non-empty subset of N. We shall denote by $\mathcal{P}_M$ the class of all systems $P = \{ p_{ij} \} ,\langle {i,j} \rangle \in N$ satisfying the following conditions: \[ p_{ij} \geqq 0\quad {\text{for}}\quad \langle {i,j} \rangle \in N, \,p_{ij} = 0\quad {\text{

On the extreme solutions of an nonlinear matrix equation

2007 American Control Conference, 2007
A quadratically convergent algorithm (QCA) for solving the extreme solutions of the matrix equation AX2+BX+C=0 was proposed by Bini and Meini. In this paper, we present a new derivation for this algorithm and a new proof for the convergence theory by using a structure-preserving transformation of a matrix pencil.

Construction of Domains with All Solutions, and the Existence of Extreme Solutions

SIAM Journal on Numerical Analysis, 1981
In this paper we construct domains with all solutions of an operator equation $Fu = 0$, and prove the existence of a minimal and maximal solution. For this one requires a suitable growth condition of F and the existence of a solution of $Fu = 0$ in intervals $[\Phi ,\Psi ]$, if $\Phi $ is a subsolrution and $\Psi $ is a supersolution for $Fu = 0$.

Extremal solutions for nonlinear neumann problems

Discussiones Mathematicae. Differential Inclusions, Control and Optimization, 2001
The authors investigate the Neumann problem in a smooth bounded domain for the equation \[ -\text{ div } \left(\|\nabla x\|^{p-2}\nabla x \right) = f(\cdot,x,\nabla x) \] with usual regularity and growth conditions on \(f\). Assuming the existence of upper and lower solutions the authors show that the set of solutions is nonvoid and directed and thus ...
