摘要:In this talk, we establish some important inequalities under a lower weighted Ricci curvature bound on Finsler manifolds. Firstly, we obtain a sharp Poincare-Lichnerowicz inequality by using integrated Bochner inequality, from which we obtain a sharp lower bound for the first eigenvalue on the Finsler manifolds. Then we establish a relative volume comparison of Bishop-Gromov type. As one of the the applications, we obtain an upper bound for volumes of the Finsler manifolds. Finally, when the S-curvature is boubded on the whole manifold, we obtain a theorem of Bonnet-Myers type on Finsler manifolds.
