Nonexistence of global solutions of □u = F(u(tt)) and of □v = F′(v(t))v(tt) in three space dimensions

The symbol □ denotes the operator ∂(2)/∂(2) - Δ in three space dimensions, and F denotes a function with F(0) = F′(0) = 0, inf F″ > 0. It is shown that u(x,t) ≡ 0, if □u = F(u(tt)) for x∈ R(3), t ≥ 0, provided u,u(t),u(tt) for t = 0 have compact support. Similarly v(x,t) ≡ 0 if □v = F′(v(t))v(tt) fo...
