چکیده

for the nonlinear initial boundary value problem of Kirchhoff equation $$ \displaylines{ u_{tt}+\Delta^2 u + M(\|\nabla u\|^2)(-\Delta u) u_{t}= \ln |u|^2,\text{ in }\Omega\times (0,T), \cr u(x,0) = u_0(x), \quad u_{t}(x,0)=u_1(x),\quad x \in \Omega, u(x,t) \frac{\partial u}{\partial \eta}(x,t)=0, \partial \Omega,\; t\geq 0, }$$ where (\Omega;\)is a bounded domain \(R^2\) with smooth \(\partial\Omega\), \(T>0\) is fixed but arbitrary real number, \(M(s)\) continuous function on \([0,+\infty)\) and \(\eta\) unit outward normal \(\partial\Omega\). Our results are obtained using Galerkin method, compactness approach, potential well corresponding to logarithmic nonlinearity, energy estimates due Nakao.

Blow-up of solutions to a class of Kirchhoff equations with strong damping and nonlinear dissipation

and many authors have studied the existence and uniqueness of global solution, the blowup of the solution (see [–] and the references therein). WhenM is not a constant function, equation (.)without the damping and source terms is often called a Kirchhoff-type wave equation; it has first been introduced by Kirchhoff [] in order to describe the nonlinear vibrations of an elastic string. When...

Positive solutions to Kirchhoff type equations with nonlinearity having prescribed asymptotic behavior

Existence and bifurcation of positive solutions to a Kirchhoff type equation ⎧⎪⎨ ⎪⎩ − ( a + b ∫ Ω |∇u|2 ) u= νf (x,u), in Ω, u= 0, on ∂Ω are considered by using topological degree argument and variational method. Here f is a continuous function which is asymptotically linear at zero and is asymptotically 3-linear at infinity. The new results fill in a gap of recent research about the Kirchhoff ...

A ug 2 01 4 Kirchhoff equations with strong damping

We consider Kirchhoff equations with strong damping, namely with a friction term which depends on a power of the “elastic” operator. We address local and global existence of solutions in two different regimes depending on the exponent in the friction term. When the exponent is greater than 1/2, the dissipation prevails, and we obtain global existence in the energy space assuming only degenerate...

Regular Solutions for Wave Equations with Super-critical Sources and Exponential-to-logarithmic Damping

We study regular solutions to wave equations with super-critical source terms, e.g., of exponent p > 5 in 3D. Such high-order sources have been a major challenge in the investigation of finite-energy (H1 × L2) solutions to wave PDEs for many years. The well-posedness question has been answered in part, but even the local existence, for instance, in 3 dimensions requires the relation p ≤ 6m/(m +...

Logarithmic decay of hyperbolic equations with arbitrary boundary damping

In this paper, we study the logarithmic stability for the hyperbolic equations by arbitrary boundary observation. Based on Carleman estimate, we first prove an estimate of the resolvent operator of such equation. Then we prove the logarithmic stability estimate for the hyperbolic equations without any assumption on an observation sub-boundary.
