Abstract

We consider the Dirichlet problem for the energy-critical heat equation (Formula presented.) where Ω is a bounded smooth domain in R 3. Let H γ(x,y) be the regular part of the Green function of -Δ-γ in Ω, where γ∈(0,λ 1) and λ 1 is the first Dirichlet eigenvalue of -Δ. Then, given a point q∈Ω such that 3γ(q)<λ 1, where (Formula presented.) we prove the existence of a non-radial global positive and smooth solution u(x, t) which blows up in infinite time with spike in q. The solution has the asymptotic profile (Formula presented.) where (Formula presented.)
