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.
