On a hyperbolic quenching problem in several dimensions. (English) Zbl 0687.35056
The author is concerned with the Cauchy problem for the hyperbolic equation \[ (E)\quad u_{tt}=\Delta_ nu+\epsilon f(u)\quad in\quad D\times (0,T),\quad D\subset {\mathbb{R}}^ n,\quad n=1,2,3. \] By a standard device, (E) is written as an equivalent system in the Hilbert space \(H^ 1_ 0(D)\times L_ 2(D)\), associated with one-parameter groups generators.
