Laplacian on measure and the Dirichlet problem
It was proposedLaplace operator version on functions on a separable real Hilbert space H(dimH 6 ∞) that is generated by the (non-negative finite Borel) measure μdefined on H. It was studied both of existence and uniqueness of solutions(including "weak" ones) of the Dirichlet peoblem for the elliptic equation ina region G that is agreed with an initial measure μ. It was given an example ofagreeing of a measure μ with a region G.

Classes of variational functionals having nonlocal K–extremum in W1,p(D) on multi-dimensional domain
In this paper the investigation scheme of nonlocal compact extremum at zero forvariational functional in Sobolev space W1,p(D), p N, on multi-dimensionalcompact domain D RN, N N, is derived. Some examples of variationalfunctionals having nonlocal K–extremum are considered.

Spectral problem with transmission conditions on curvilinear interface
This paper deals with a spectral problem arising in a problem of small motions ofa system "ideal capillary fluid–gas" in a rectangular vessel with the solid walls.We suppose that a gas density is exponentially stratified opposite to the directionof gravitational forces and conjugation conditions for potential displacement areformulated on the fluid surface which is not horizontal at rest. A projectionmethod for finding a generalized solution is offered.

Abstract mixed boundary and spectral transmission problems
On the basis of the abstract Green’s formula for the triple of Hilbert spacesand the generalized Green’s formula for the Laplace operator we consider a newclass of mixed boundary value and spectral transmission problems.

Weak and generalized solutions of the abstract cauchy problem
Weconsider three types of solutions (weak, generalized with respect to t and withrespect to a random variable) for the infinite dimensional stochastic Cauchyproblem X(t) = AX(t) + BW(t), t 0,X(0) = ζ, with A being the generatorof a regularized semigroup in a Hilbert space H and a white noise W in anotherHilbert space H, B ∈ L(H,H). It is proved coincidence of the solutions underthe conditions they exist.

On the solution of three-criteria problem under uncertainty
In this paper the definition of guaranteed solution for three-criteria problemunder uncertainty is introduced. New solution is based on the method ofdecision-making in hierarchical two-level game. The conditions of existence areformulated. The example is given.

Guaranteed on risk solution in problem of sum distribution into three deposits (in rubles, dollars and euros)
We are looking at problemsof sum distribution (in rubles) into three deposits (in rubles, dollars and euros)in order to obtain the maximum annual income (in terms of rubles). Thedecision maker (investor) does not know the real dollar and the euro rates atthe end of the year, and has to look at some possible rate boundaries or limitsfor them. The solution of this problem depends on the readiness of the decisionmakerto take risks. The contents of this article are the ways to construct thedecisions of guaranteed risks onto account. This paper is actually devoted toconstructing of a guaranteed on risk solution.

Guaranteed in outcomes and risks solution for single-criterion problem
Concept of Pareto-guaranteed in outcomes and risks solution for singlecriterionproblem under uncertainty is proposed. It is based on a modificationof the maximin. Explicit solution for the problem of a single contribution to thediversification of ruble and foreign currency deposit is found.
