Magnetohydrodynamic channel flow and variational principles
International Journal of Mathematics and Mathematical Sciences, 1987 This paper deals with magnetohydrodynamic channel flow problems. Attention is given to a variational principle where the boundary conditions are incorporated via a suitable functional which is stationary at the solution of the given problem; the trial ...

Some Variational Principles for Coupled Thermoelasticity
Journal of Engineering, 2013 The nonlinear thermoelasticity of type II proposed by Green and Naghdi is considered. The thermoelastic structural model is formulated in a quasistatic range, and the related thermoelastic variational formulation in the complete set of state variables is

Neumann's method to solve boundary problems of elastic thin shells [PDF]
Компьютерные исследования и моделирование, 2015 This paper studies possibilities to use Neumann's method to solve boundary problems of elastic thin shells. Variational statement of statical problems for shells allows examining the problems within the space of distributions.

Bergsoniana, 2021 Given Bergson’s commitment to a dynamic conception of time and an open future it seems likely that he would not have welcomed developments in physics which suggest that we live in an eternal four-dimensional block-universe.

A Variational Principle in Krein Space [PDF]
Transactions of the American Mathematical Society, 1994 A variational characterization, involving a max-inf of the Rayleigh quotient, is established for certain eigenvalues of a wide class of definitizable selfadjoint operators Q in a Krein space.

Symmetries, variational principles, and quantum dynamics
Discrete Dynamics in Nature and Society, 2004 We describe the role of symmetries in formation of quantum dynamics. A quantum version of d'Alembert's principle is proposed to take into account the symmetry constrains more exact.

Ingress of Li into Solid Electrolytes: Cracking and Sparsely Filled Cracks
Small Structures, 2023 The growth of Li dendrites in a solid electrolyte is commonly idealized by a pressure‐filled crack. Recent observations in both garnet and sulfide electrolytes show that sparsely filled cracks exist prior to shorting of the cell, thereby invalidating ...

Nonlocal Variational Principles with Variable Growth
Journal of Function Spaces, 2014 This paper is concerned with the functional J defined by J(u)=∫Ω×ΩW(x,y,∇u(x),∇u(y))dx dy, where Ω⊂ℝN is a regular open bounded set and W is a real-valued function with variable growth.

Mathematical models of nonlinear longitudinal-cross oscillations of object with moving borders
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The nonlinear formulation of problems for describing longitudinal-cross oscillations of objects with moving borders is noted. These mathematical models consist of a system of two nonlinear partial differential equations with the higher time derivative of
