متن کاملHilbert Manifolds without Epiconjugate Points
This theorem had been proved by Myers [6] under the assumption that M was analytic, and this assumption was essential in his proof. Kobayashi, and also Helgason in his book [3], showed that analytic ity was superfluous and could be replaced with mere smoothness of a sufficiently high order. We want to consider this theorem for infinite-dimensional Riemannian Hubert manifolds. We do not know if ...
متن کاملExponential Growth of Spaces without Conjugate Points
An n-dimensional polyhedral space is a length space M (with intrinsic metric) triangulated into n-simplexes with smooth Riemannian metrics. In the definitions below, we assume that the triangulation is fixed. The boundary of M is the union of the (n− 1)-simplexes of the triangulation that are adjacent to only one (n− 1)-simplex. As usual, a geodesic in M is a naturally parametrized locally shor...
متن کاملSufficient conditions for convexity in manifolds without focal points
In this paper, local, global, strongly local and strongly global supportings of subsets in a complete simply connected smooth Riemannian manifold without focal points are defined. Sufficient conditions for convexity of subsets in the same sort of manifolds have been derived in terms of the above mentioned types of supportings.
