 Blow-up rate for the semi-linear wave equation in bounded domain Bull. Korean Math. Soc. 2015 Vol. 52, No. 1, 173-182 https://doi.org/10.4134/BKMS.2015.52.1.173Printed January 31, 2015 Chuangchuang Liang and Pengchao Wang Capital Normal University, Northeast Normal University Abstract : In this paper, the blow-up rate of $L^2$-norm for the semi-linear wave equation with a power nonlinearity is obtained in the bounded domain for any $p>1$. We also get the blow-up rate of the derivative under the condition \$1 Keywords : semi-linear wave equation, blow-up rate, bounded domain MSC numbers : 35L05, 35B44 Downloads: Full-text PDF
