Results from a Nonlinear Wave Equation with Acoustic and Fractional Boundary Conditions Coupling by Logarithmic Source and Delay Terms: Global Existence and Asymptotic Behavior of Solutions

open access: yesMathematics
The nonlinear wave equation with acoustic and fractional boundary conditions, coupled with logarithmic source and delay terms, is significant for its ability to model complex systems, its contribution to the advancement of mathematical theory, and its ...

Global existence for semilinear parabolic systems.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1985
This paper studies the problem of global existence for strongly coupled semilinear parabolic systems of arbitrary even order under linear time- dependent boundary conditions. In particular it is shown that there exist classical global solutions provided the nonlinearity satisfies appropriate polynomial growth restrictions and a priori estimates in some

Nonlinear heat equation with viscoelastic term: Global existence and blowup in finite time

open access: yesDemonstratio Mathematica
In this study, we investigate a nonlinear heat equation incorporating both a viscoelastic term and a reaction-diffusion term that depends on space-time variables.

Global existence and long-time behavior of entropy weak solutions to a quasilinear hyperbolic blood flow model

open access: yesNetworks and Heterogeneous Media, 2011
This paper is concerned with an initial-boundary value problem on bounded domains for a onedimensional quasilinear hyperbolic model of blood flow with viscous damping.It is shown that $L^\infty$ entropy weak solutions exist globally in timewhen the ...

Global existence for Maxwell–Bloch systems

open access: yesJournal of Differential Equations, 2005
The author proves an existence and uniqueness result for the energy solution of the Maxwell-Bloch system with arbitrary initial vector in \(L^2(\mathbb R^3)\times L^2(\mathbb R^3)\times (L^2\cap L^\infty)(\mathbb R^3)\) verifying the conservation of current and charge.

Global existence of near-affine solutions to the compressible Euler equations

open access: yes, 2019
We establish global existence of solutions to the compressible Euler equations, in the case that a finite volume of ideal gas expands into vacuum. Vacuum states can occur with either smooth or singular sound speed, the latter corresponding to the so ...

Second order p-evolution equations with critical nonlinearity

open access: yesBruno Pini Mathematical Analysis Seminar
In this paper, we study critical nonlinearities for global small data solutions to the plate equation and other second order p-evolution equations, possibly under the action of a noneffective dissipative term.
