Stochastic Duality and Eigenfunctions [PDF]
, 2019 We start from the observation that, anytime two Markov generators share an eigenvalue, the function constructed from the product of the two eigenfunctions associated to this common eigenvalue is a duality function. We push further this observation and provide a full characterization of duality relations in terms of spectral decompositions of the ...

ON STABILIZATION PROBLEM FOR A LOADED HEAT EQUATION: THE TWO-DIMENSIONAL CASE
Вестник КазНУ. Серия математика, механика, информатика, 2021 One of the important properties that characterize the behavior of solutions of boundary value problems for differential equations is stabilization, which has a direct relationship with the problems of controllability.

Estimates for Dirichlet Eigenfunctions [PDF]
Journal of the London Mathematical Society, 1999 Estimates for the Dirichlet eigenfunctions near the boundary of an open, bounded set in euclidean space are obtained. It is assumed that the boundary satisfies a uniform capacitary density condition.

Eigenfunctions in Finsler Gaussian solitons
Open Mathematics, 2023 Gaussian solitons are important examples in the theory of Riemannian measure space. In the first part, we explicitly characterize the first eigenfunctions of the drift Laplacian in a Gaussian shrinking soliton, which shows that apart from each coordinate

European Journal of Organic Chemistry, EarlyView.Molecules with unpaired electrons, also known as open‐shell systems, are key intermediates in several light‐mediated or metal‐catalyzed transformations in organic chemistry. However, modeling this chemistry by density functional theory calculations is challenging.

On a boundary problem for the fourth order equation with the third derivative with respect to time
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 In this paper, we consider a boundary value problem in a rectangular domain for a fourth-order homogeneous partial differential equation containing the third derivative with respect to time. The uniqueness of the solution of the stated problem is proved
