چکیده

The problem under consideration is as follows. Let I(u, ω) be a random functional of u , u is an element of some functional space R, ω being a random parameter. For each ω, one seeks for a minimum value of the functional I(u, ω). The minimizing element, ǔ, of the functional I(u, ω) is random since it depends on ω. We are interested in determining the probability density function of some deterministic functional, L(ǔ), of the minimizing element. In such general setting one can hardly expect a meaningful answer. In this note a very special case of the problem is considered when I(u, ω) is a quadratic functional,

Distribution of minimum values of stochastic functionals

Some mathematical problems of mechanics and physics have a form of the following variational problem. There is a functional, I, which is a sum of some quadratic positive functional and a linear functional. The quadratic functional is deterministic. The linear functional is a sum of a large number, N , of statistically independent linear functionals. The minimum value of the functional, I; is ra...

Existence of three solutions for a class of fractional boundary value systems

In this paper, under appropriate oscillating behaviours of the nonlinear term, we prove some multiplicity results for a class of nonlinear fractional equations. These problems have a variational structure and we find three solutions for them by exploiting an abstract result for smooth functionals defined on a reflexive Banach space. To make the nonlinear methods work, some careful analysis of t...

A VARIATIONAL APPROACH TO THE EXISTENCE OF INFINITELY MANY SOLUTIONS FOR DIFFERENCE EQUATIONS

The existence of infinitely many solutions for an anisotropic discrete non-linear problem with variable exponent according to p(k)–Laplacian operator with Dirichlet boundary value condition, under appropriate behaviors of the non-linear term, is investigated. The technical approach is based on a local minimum theorem for differentiable functionals due to Ricceri. We point out a theorem as a spe...

Optimality conditions for approximate solutions of vector optimization problems with variable ordering structures

‎We consider nonconvex vector optimization problems with variable ordering structures in Banach spaces‎. ‎Under certain boundedness and continuity properties we present necessary conditions for approximate solutions of these problems‎. ‎Using a generic approach to subdifferentials we derive necessary conditions for approximate minimizers and approximately minimal solutions of vector optimizatio...

Minimization of energy functionals applied to some inverse problems

We consider a general class of problems of minimization of convex integral functionals subject to linear constraints. Using Fenchel duality, we prove the equality of the values of the minimization problem and its associated dual problem. This equality is a variational criterion for the existence of solution to a large class of inverse problems entering the class of generalized Fredholm integral...
