本文对方程Δu(x)+h(x)u(x)=0,在无边界完备黎曼流形上得到一个具有非负Ricci曲率的Liouville型定理,其中条件limr→∞r−1.supx ∈ Bp(r)|Δh(x)|= 0和h ≥ 0。-T Yau(Acta Math.156(1986),153-201)和Jiayu Li(J. Funct. Anal. 100(1991),233-256)分别被一个比它们更弱的条件所取代,即limr→∞r−2·infx∈Bp(r)h(x)= 0。
Abstract In this paper, we derive a Liouville type theorem on a complete Riemannian manifold without boundary and with nonnegative Ricci curvature for the equation Δu(x)+h(x)u(x)=0, where the conditions limr→∞r−1.supx ∈ Bp(r)|Δh(x)| = 0 and h ≥ 0 imposed by P. Li and S. -T. Yau (Acta Math. 156 (1986), 153-201) and Jiayu Li (J. Funct. Anal. 100 (1991), 233-256), respectively, are replaced by a weaker condition than both of them, namely, limr→∞r−2·infx∈Bp(r)h(x) = 0.
