BOUNDARY-VALUE PROBLEMS WITH GENERALIZED GLUING CONDITIONS FOR A LOADED DIFFERENTIAL EQUATION WITH A PARABOLIC-HYPERBOLIC OPERATOR [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2016
In the present work we study the unique solvability of local boundary value problems with generalized gluing conditions for the third order differential equation with a loaded parabolic-hyperbolic operator.

On periodic solutions of a semilinear hyperbolic parabolic equation [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1992
Uniqueness and regularity of periodic solutions to the semilinear dissipative wave equation with small parameter ∈ > 0,are investigated when g(u) has a certain ‘critical’ nonlinearity.

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]

open access: yes, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

Quasilinear Hyperbolic–Parabolic Equations of One-Dimensional Viscoelasticity

open access: yesJournal of Differential Equations, 1996
The aim of this paper is to give sufficient conditions for a nonlinear stress function \(n= n(s, w_s, w_{st})\) guaranteeing global-in-time existence of solutions of initial-value problem for the quasilinear hyperbolic-parabolic equation \(\varrho w_{tt}= n(s, w_s, w_{st})_s+ f(s, t)\) describing longitudinal motions of a viscoelastic rod.

Uniform stabilization of a coupled structural acoustic system by boundary dissipation

open access: yesAbstract and Applied Analysis, 1998
We consider a coupled PDE system arising in noise reduction problems. In a two dimensional chamber, the acoustic pressure (unwanted noise) is represented by a hyperbolic wave equation.

The entropy solution of a hyperbolic-parabolic mixed type equation [PDF]

open access: yesSpringerPlus, 2016
The entropy solution of the equation [Formula: see text]is considered. Besides the usual initial value, only a partial boundary value is imposed. By choosing some special test functions, the stability of the solutions is obtained by Kruzkov's bi-variables method, provided that [Formula: see text] is an unit n-dimensional cube or the half space.
