Abstract

We consider positive solutions for the fractional heat equation with critical exponent {ut=-(-Δ)su+un+2sn-2sinΩ×(0,∞),u=0on(Rn\Ω)×(0,∞),u(·,0)=u0inRn,where Ω is a smooth bounded domain in Rn, n> 4 s, s∈ (0 , 1) , u: Rn× [0 , ∞) → R and u0 is a positive smooth initial datum with u0|Rn\Ω=0. We prove the existence of u0 such that the solution blows up precisely at prescribed distinct points q1, … , qk in Ω as t→ + ∞. The main ingredient of the proofs is a new inner–outer gluing scheme for the fractional parabolic problems. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.
