Nonlinear parabolic equations with Robin boundary conditions and Hardy-Leray type inequalities

Abstract

We are primarily concerned with the absence of positive solutions of the following problem, ⎧ ∂u ⎪⎨ ∂t=Δ(um ) + V (x)um + λuq in Ω × (0, T ), u(x, 0) = u0 (x) ≥ 0 in Ω, ⎪⎩ ∂u ∂ν=β(x)u on ∂Ω × (0, T ), where 0 < m < 1, V ∈ L1loc(Ω),β∈ L1loc(∂Ω), λ ∈ R, q > 0, Ω ⊂ RN is a bounded open subset of RN with smooth boundary ∂Ω, and∂u is the ∂ν outer normal derivative of u on ∂Ω. Moreover, we also present some new sharp Hardy and Leray type inequalities with remainder terms that provide us concrete potentials to use in the partial differential equation of our interest.
