In this paper,the authors study the gradient estimates for positive weak solutions to the following p-Laplacian equation △pu+auσ=0 on complete noncompact Riemannian manifold,where a,σ are two nonzero real constants with p≠2.Using the gradient estimate,they can get the corresponding Lionville theorem.On the other hand,by virtue of the Poincare inequality,they also obtain a Liouville theorem under some integral conditions with respect to positive weak solutions. 相似文献

On the Radial Ground State of p-Laplacian Equation Involving Super-critical or Critical Exponents 下载免费PDF全文
In this paper, we consider the existence and uniqueness of the radial ground state to the following p-Laplacian equation involving super-critical or critical exponents: Δ_pu + u^q - |Du|^σ = 0, x ∈ R^n, 2 ≤ p < n, q ≥ [n(p - 1) + p]/(n - p), σ > 0. Applying the shooting argument, the Schauder's fixed point theorem and some delicate estimates of auxiliary functions, we study the influence of the parameters n, p, q, σ on the existence and uniqueness of the radial ground state to the above p-Laplacian equation. 相似文献

In this note we obtain a new a priori estimate for the very weak solutions of p-Laplacian type equations with VMO coefficients when p is close to 2, and then prove that the very weak solutions of such equations are the usual weak solutions. Our approath is based on the Hodge decomposition and the L^p-estimate for the corresponding linear equations. And this also provides a simpler proof for the results in [1]. 相似文献

Nodal Solutions of a p-Laplacian Equation 总被引:2,自引:0,他引:2
We prove that the p-Laplacian problem p u = f(x, u),with u on a bounded domain RN, with p > 1 arbitrary, has a nodal solution providedthat f : x R R is subcritical, and f(x, t) / |t|p 2 is superlinear. Infinitely many nodal solutions are obtainedif, in addition, f(x, t) = f(x, t). 2000 MathematicsSubject Classification 35J20, 35J65, 58E05. 相似文献

We investigate the $p$-Laplace heat equation $u_t-Delta_p u=ζ(t)f(u)$ in a bounded smooth domain. Using differential-inequality arguments, we prove blow-up results under suitable conditions on $ζ, f$, and the initial datum $u_0$. We also give an upper bound for the blow-up time in each case. 相似文献
