The purpose of this paper is twofold. First is the study of the nonexistence of positive solutions of the parabolic problem {∂u∂t=Δpu+V(x)up-1+λuqinΩ×(0,T),u(x,0)=u0(x)≥0inΩ,|∇u|p-2∂u∂ν=β|u|p-2uon∂Ω×(0,T),where Ω is a bounded domain in RN with smooth boundary ∂Ω, Δpu= div (| ∇ u| p-2∇ u) is the p-Laplacian of u, V∈Lloc1(Ω), β∈Lloc1(∂Ω), λ∈ R, the exponents p and q satisfy 1 < p< 2 , and q> 0. Then, we present some sharp Hardy and Leray type inequalities with remainder terms that provide us concrete potentials to use in the partial differential equation we are interested in.
