This article generalizes the formulas of Gauss-Ostrogradskii type for semibasic vector fields from Riemannian manifolds to real Finsler manifolds and obtains some formulas of Gauss-Ostrogradskii type for Finsler vector fields which are expressed in terms of the vertical and horizontal derivatives of the Cartan connection in real Finsler manifolds. 相似文献

Using non-linear connection of Finsler manifold M, the existence of local coordinates which is normalized at a point x is proved, and the Laplace operator A on 1-form of M is defined by non-linear connection and its curvature tensor. After proving the maximum principle theorem of Hopf-Bochner on M, the Bochner type vanishing theorem of Killing vectors and harmonic 1-form are obtained. 相似文献

本文给出了强K(a)hler-Finsler流形上中值Laplace算子的一些性质,如自伴性质,散度形式等.与K(a)hler流形上利用逆变基本张量[11]及其在Finsler流形上的变形[5,10]作为密度函数定义流形上的逐点内积及整体内积不同,作者利用强K(a)hler-Finsler流形上的逆变密切Kahler度量作为密度函数定义了流形上的逐点内积和整体内积,并定义了强K(a)hler-Finsler流形上的Hodge-Laplace算子,它可看作函数情形中值Laplace算子的推广. 相似文献

设M为n维复流形,F为M上的强拟凸的复Finsler度量,M是M的m维复子流形,F是F在M上诱导的复Finsler度量,D为(M,F)上的复Rund联络.本文证明了(1)(M,F)上的诱导复线性联络△↓的全纯曲率与(M,F)上的复Rund联络△↓^*的全纯曲率相同;(2)联络△↓^*的全纯曲率不超过联络D的全纯曲率;(3)(M,F)是(M,F)的全测地复Finsler子流形的充分必要条件是(M,F)的第2基本形式B(.,.)的适当形式的缩并为零,即B(x,l)=0.本文的证明主要利用复Finsler子流形(M,F)的Gauss,Codazzi和Ricci方程. 相似文献

设M是复流形,具有复(α,β)度量F=αφ(|β|/α),其中α为M上的Hermite度量,β为M上的(1,0)形式。本文得到与F相联系的复非线性联络系数Гiμ^i的表达式,且证明了:若β为M上的全纯(1,0)形式,并且关于α的Hermite联络γij^k(z)平行,则F是M上的复Berwald度量;若α是M上的Kaihler度量,则F是M上的强Kahler Finsler度量. 相似文献

By means of the Hermitian metric and Chern connection, Qiu [4] obtained the Koppelman-Leray-Norguet formula for (p, q) differential forms on an open set with C^1 piecewise smooth boundary on a Stein manifold, and under suitable conditions gave the solutions of δ^--equation on a Stein manifold. In this article, using the method of Range and Siu [5], under suitable conditions, the authors complicatedly calculate to give the uniform estimates of solutions of δ^--equation for (p, q) differential forms on a Stein manifold. 相似文献

A vector bundle F over the tangent bundle TM of a manifold M is said to be a Finsler vector bundle if it is isomorphic to the pull-back π^*E of a vector bundle E over M([1]). In this article the authors study the h-Laplace operator in Finsler vector bundles. An h-Laplace operator is defined, first for functions and then for horizontal Finsler forms on E. Using the h-Laplace operator, the authors define the h-harmonic function and ho harmonic horizontal Finsler vector fields, and furthermore prove some integral formulas for the h-Laplace operator, horizontal Finsler vector fields, and scalar fields on E. 相似文献
