PurposeIn Japan, health-care systems have long been supported by physicians' long working hours. To solve this problem, there is an urgent need to improve the working environment for physicians while practicing patient-centered medicine and controlli

We prove a rigidity theorem for Killing vector fields of a manifold with almost nonpositive Ricci curvature, which is a generalization of Bochner’s classical results.

We estimate the order of isometry groups of compact Riemannian manifolds which have negative Ricci curvature except for small portions, in terms of geometric quantities.

This paper explores and ties together three themes. The first is to establish regularity of a metric tensor, on a manifold with boundary, on which there are given Ricci curvature bounds, on the manifold and its boundary, and a Lipschitz bound on the

Three themes are treated in the results announced here. The first is the regularity of a metric tensor, on a manifold with boundary, on which there are given Ricci curvature bounds, on the manifold and its boundary, and a Lipschitz bound on the mean

We give two methods for constructing isospectral graphs. As an application, families of infinite pairs of regular isospectral graphs with different magnification are presented.
