To the solution of the Solonnikov-Fasano problem with boundary moving on arbitrary law x = γ(t).

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper we study the solvability of the boundary value problem for the heat equation in a domain that degenerates into a point at the initial moment of time. In this case, the boundary changing with time moves according to an arbitrary law x = γ(t)

Shifts in Redox Formal Potentials Accompanying the Incorporation of Cationic Complexes in Perfluoro Polycarboxylate and Polysulfonate Coatings on Graphite Electrodes [PDF]

open access: yes, 1984
The formal potentials of several redox couples incorporated in coatings of a perfluoropolycarboxylate on graphite electrodes were measured and compared with the formal potentials of the same couples in homogeneous solution.

Effect of Torso Non-Homogeneities in the quasi-static inverse problems arising in electrocardiology

open access: yesMoroccan Journal of Pure and Applied Analysis, 2019
In the present paper, an homogeneous and non-homogeneous inverse problem constrained by the stationary problem in electrocardiology representing the heart, lungs surfaces, and torso model is investigated.

Isospin asymmetry in holographic baryonic matter

open access: yesSciPost Physics, 2021
We study baryonic matter with isospin asymmetry, including fully dynamically its interplay with pion condensation. To this end, we employ the holographic Witten-Sakai-Sugimoto model and the so-called homogeneous ansatz for the gauge fields in the bulk

A class of random fields on complete graphs with tractable partition function

open access: yes, 2013
The aim of this short note is to draw attention to a method by which the partition function and marginal probabilities for a certain class of random fields on complete graphs can be computed in polynomial time.

On the distribution of integral functionals of a homogeneous diffusion process

open access: yesModern Stochastics: Theory and Applications, 2014
In this article, we study homogeneous transient diffusion processes. We provide the basic distributions of their local times. It helps to get exact formulas and upper bounds for the moments, exponential moments, and potentials of integral functionals of ...

On the behavior at collisions of solutions to Schr\"odinger equations with many-particle and cylindrical potentials

open access: yes, 2011
The asymptotic behavior of solutions to Schr\"odinger equations with singular homogeneous potentials is investigated. Through an Almgren type monotonicity formula and separation of variables, we describe the exact asymptotics near the singularity of ...

Berry's phase for compact Lie groups [PDF]

open access: yes, 2000
The Lie group adiabatic evolution determined by a Lie algebra parameter dependent Hamiltonian is considered. It is demonstrated that in the case when the parameter space of the Hamiltonian is a homogeneous K\"ahler manifold its fundamental K\"ahler ...
