摘要

研究了一类具有对数非线性的伪抛物型$ p $-Kirchhoff方程的初边值问题。通过证明该问题半流下不稳定集的不变性,采用Levine的凹性论证,建立了该问题的一般有限时间爆破判据,特别表明对于某些初始数据,该问题在任意高的初始能级上允许有限时间爆破解。此外,爆破解决方案的寿命是从上面估计的。

Blow-up for a pseudo-parabolic $ p $-Kirchhoff equation with logarithmic nonlinearity
In this paper, an initial boundary value problem for a pseudo-parabolic type $ p $-Kirchhoff equation with logarithmic nonlinearity is investigated. By proving the invariance of the unstable set under the semi-flow of this problem and adopting the Levine's concavity argument, a general finite time blow-up criterion for this problem is established, which in particular implies that for some initial data, the problem admits finite time blow-up solutions at arbitrarily high initial energy level. Moreover, the lifespan of the blow-up solutions is estimated from above.

期刊介绍: EECT is primarily devoted to papers on analysis and control of infinite dimensional systems with emphasis on applications to PDE''s and FDEs. Topics include: * Modeling of physical systems as infinite-dimensional processes * Direct problems such as existence, regularity and well-posedness * Stability, long-time behavior and associated dynamical attractors * Indirect problems such as exact controllability, reachability theory and inverse problems * Optimization - including shape optimization - optimal control, game theory and calculus of variations * Well-posedness, stability and control of coupled systems with an interface. Free boundary problems and problems with moving interface(s) * Applications of the theory to physics, chemistry, engineering, economics, medicine and biology
