We will investigate the nonexistence of positive solutions for the following nonlinear parabolic partial differential equation: ∂u/∂t=ℒu+V(w)up−1 in Ω×(0,T), 1

The main goal of this paper is twofold. The first one is to investigate the nonexistence of positive solutions for the following nonlinear parabolic partial differential equation on a noncompact Riemannian manifold M, $$\begin{aligned} {\left\{ \begi

We are primarily concerned with the absence of positive solutions of the following problem, \[ { ∂ u ∂ t = Δ ( u m ) + V ( x ) u m + λ u q a m p ; in Ω × ( 0 , T ) , u ( x , 0 ) = u 0 ( x ) ≥ 0 a m p ; in Ω , ∂ u ∂ ν = β ( x ) u a m

In this paper, we derive a sufficient condition on a pair of nonnegative weight functions ? and w in ?m+k so that the general weighted Hardy type inequality with a remainder term (Formula Presented) is the sub-elliptic gradient. It is worth emphasizi

In this paper we present new results on two-weight Hardy, Hardy–Poincare and Rellich type inequalities with remainder terms on a complete noncompact Riemannian Manifold M. The method we use is flexible enough to obtain more weighted Hardy type ineq
