Öz

(ℵ,F) manifoldu forward tam, bağlantılı ve n≥2 boyutlu bir Finsler manifold olsun. Bu çalışmada, Riemann manifoldlarında elde edilen Ambrose kompaktlık teoremi, ağırlıklı Ricci eğriliği kullanılarak Finsler manifoldlara genişletilmiştir. İstenilen sonuçların kanıtları için Bochner Weitzenböck formülü ve uygun dizi seçimleri kullanılmıştır.

A Note on Finsler Version of Ambrose Theorem

Öz

Let (ℵ,F) be a forward complete and connected Finsler manifold of dimensional n≥2. In this study, we extend Ambrose’s compactness theorem in Riemannian manifolds to Finsler manifolds by using the weighted Ricci curvature. We use the Bochner Weitzenböck formula and suitable sequence choices for the proofs of the desired results.
