Harmonic maps between riemannian manifolds are very important in both differential geometry and mathematical physics . riemannian manifold and finsler manifold are metric measure space , so we can study harmonic map between finsler manifolds by the theory of harmonic map on general metric measure space , it will be hard to study harmonic map between finsler manifolds by tensor analysis and it will be no distinctions between the theory of harmonic map on finsler manifold and that of metric measure space . harmonic map between riemannian manifold also can be viewed as the harmonic map between tangent bundles of source manifold and target manifold 黎曼流形間的調(diào)和映射是微分幾何和數(shù)學物理的重要內(nèi)容。黎曼流形和finsler流形都是度量空間,自然可利用一般度量空間調(diào)和映射的理論討論finsler流形間的調(diào)和映射。但由于控制finsler流形性質(zhì)的各種張量一般情況下很難應用到一般度量空間調(diào)和映射的理論中,使得這樣的討論大都是形式上的,并與一般度量空間調(diào)和映射的理論區(qū)別不大。
