Let G:\mathbbR→ R be a continuous function. In the first part of this paper, we investigate sufficient conditions on G such that \G(f):f∈ Kp,qαFβs\⊂ Kp,qαFβs holds. Here Kp,qαFβs are Herz-type Triebel-Lizorkin spaces. These spaces unify and generalize many classical function spaces such as Lebesgue spaces of power weights, Sobolev and Triebel-Lizorkin spaces of power weights. In the second part of this paper we will study local and global Cauchy problems for the semilinear parabolic equations ∂ tu-Δu=G(u) with initial data in Herz-type Triebel-Lizorkin spaces. Our results cover the results obtained with initial data in some know function spaces such us fractional Sobolev spaces. Some limit cases are given.
