    A 3-dimensional graph-manifold consists of simple blocks that are products of compact surfaces with boundary by the circle. Its global structure may be as complicated as desired and is described by a graph, which can be an arbitrary graph. A metric of nonpositive curvature on such a manifold, if...

    Let (M, h, ∇) be a statistical manifold of dimension n(≥ 2). Then we show that (M, h, ∇) is of constant curvature if and only if the tangent bundle TM over M with complete lift statistical structure (hC, ∇C) is conformally-projectively flat.

    The geometry of the tangent bundle is used to define a particular class of metrics called adapted bi-conformal. These metrics are defined and studied on the holomorphic cotangent bundle of a K�hler manifold. K�hlerian adapted bi-conformal metrics are totally classified and their...

    In [5] we give a theorem about projectivities between three line bundles in the projective plane with an almost trivial proof, and with a lot of special cases among which the theorems of Desargues, Pappus-Pascal, Pascal and many other lesser known results. In this paper we retake this idea, but...

    In this paper, we show that the Pesin set of an expansive geodesic flow in compact manifold with no conjugate points and bounded asymptote coincides a.e with an open and dense set of the unit tangent bundle. We also show that the set of hyperbolic periodic orbits is dense in the unit tangent bundle.
