This paper is devoted to the study of the Cauchy problem for a semilinear heat equation with nonlinear term presenting a nonlinear source centered in a closed region of the spatial domain Ω. We assume that Ω ⊂ R nis either a smooth bounded domain or the whole spaceR n , n ≥ 2 . The initial datau 0is assumed to belong to the Lebesgue spaceL r( Ω ) .
