Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020 We consider a nonlocal boundary value problem for non-stationary composite type equation of the third order. The values of function and its derivatives up to the second order on the boundary are given as a linear combination.

Potential-Based Large-Signal Stability Analysis in DC Power Grids With Multiple Constant Power Loads
IEEE Open Access Journal of Power and Energy, 2022 The increasing adoption of power electronic devices may lead to large disturbance in DC power grids. Traditionally, the Brayton-Moser mixed potential theory is utilized to address large-signal stability (LSS) analysis.

Eigenvalue asymptotics for potential type operators on Lipschitz surfaces of codimension greater than 1 [PDF]
Opuscula Mathematica, 2018 For potential type integral operators on a Lipschitz submanifold the asymptotic formula for eigenvalues is proved. The reasoning is based upon the study of the rate of operator convergence as smooth surfaces approximate the Lipschitz one.

Application of low-order potential solutions to higher-order vertical traction boundary problems in an elastic half-space [PDF]
Royal Society Open Science, 2018 New solutions of potential functions for the bilinear vertical traction boundary condition are derived and presented. The discretization and interpolation of higher-order tractions and the superposition of the bilinear solutions provide a method of ...

Elastic Stress Field beneath a Sticking Circular Contact under Tangential Load
Solids, 2023 Based on a potential theoretical approach, the subsurface stress field is calculated for an elastic half-space which is subject to normal and uniaxial tangential surface tractions that—in the case of elastic decoupling—correspond to rigid normal and ...

Monogenic Functions in a Finite-Dimensional Semi-Simple Commutative Algebra
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 We obtain a constructive description of monogenic functions taking values in a finite-dimensional semi-simple commutative algebra by means of holomorphic functions of the complex variable.

Integral theorems for the quaternionic G-monogenic mappings
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 In the paper [1] considered a new class of quaternionic mappings, so- called G-monogenic mappings. In this paper we prove analogues of classical integral theorems of the holomorphic function theory: the Cauchy integral theorems for surface and ...

Potential NRQCD: an effective theory for heavy quarkonium [PDF]
, 1999 Within an effective field theory framework we study heavy-quark--antiquark systems with a typical distance between the heavy quark and the antiquark smaller than $1/\Lambda_{\rm QCD}$. A suitable definition of the potential is given within this framework,
