Blow-Up of Solutions and Estimate the Upper Bound of Life Span for Semilinear Wave Equation in Three-Dimensional Space
摘要
Abstract
The initial boundary value problem for semilinear wave equation on exterior domain in 3-D was studied by using test function method.The results show that blow up of solutions and the upper bound of life span estimate are established,no matter how small the data are.And the explicit expression the test functionΦ0 (x)is founded.关键词
