Blow-Up of Positive Solutions to Wave Equations in High Space Dimensions

Hiroyuki Takamura, Mohammad Rammaha, Hiroshi Uesaka +1

This paper is concerned with the Cauchy problem for the semilinear wave equation: $u_{tt}-Δu=F(u) \ \mbox{in} \ R^n\times[0, \infty)$, where the space dimension $n\ge 2$, $F(u)=|u…
