Well-posedness of the Dirichlet and Poincaré problems for one class of hyperbolic equations in a multidimensional domain

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
In early works the author studied the Dirichlet and Poincaré problems for multidimensional hyperbolic equations, which shows the well-posedness of these problems in cylindrical domains, significantly dependent on the height of the considered cylindrical ...

On the Truncated Multidimensional Moment Problems in ${\mathbb{C}}^n$

Axioms, 2022
We consider the problem of finding a (non-negative) measure μ on B(Cn) such that ∫Cnzkdμ(z)=sk, ∀k∈K. Here, K is an arbitrary finite subset of Z+n, which contains (0,…,0), and sk are prescribed complex numbers (we use the usual notations for multi ...

Constructing Composite Indicators Through Extreme Values Reductions-Ordered Weighted Averaging: Human Development Index

IEEE Access
The Human Development Index is a complex social phenomenon composed of multiple criteria. While many studies are concerned with dealing with outliers in the representation of this composite indicator, the problem of extreme values is overlooked.

Multidimensional Contact Problems in Thermoelasticity [PDF]

SIAM Journal on Applied Mathematics, 1998
Summary: We consider dynamic and quasi-static thermoelastic contact problems in \({\mathbb R}^n\) modeling the evolution of temperature and displacement in an elastic body that may come into contact with a rigid foundation. The existence of solutions to these dynamic and quasi-static nonlinear problems and the exponential stability of the solutions are
