摘要
若Hadamard流形中的完备非紧可定向子流形具有有限全曲率且截面曲率非正,证明了当光滑函数u的Lp范数有限时,任何的p-调和函数一定是一个常数(p≥2).
Let m-dimensional complete non-compact oriented submanifolds in Hadamard manifolds have finite total curvature and non-positive sectional curvature. Further,it is assumed that the first eigenvalue of Laplacian in M is bounded by an appropriate constant. Then,when the norm of Lpof the smooth function u is finite,any p-harmonic function must be a constant( p≥ 2).
