Spectral properties of stationary solutions of the nonlinear heat equation
In this paper, we prove that if Ψ is a radially symmetric, signchanging stationary solution of the nonlinear heat equationin the unit ball of R N , N = 3, with Dirichlet boundary conditions, then the solution of (NLH) with initial value λΨ blows up in finite time if |λ …
