Chen [3] established a sharp inequality for the warping function of a warped product submanifold in a Riemannian space form in terms of the squared mean curvature.. For a survey
Recently, Tu and Deng proposed a combinatorial conjecture about binary strings, and, on the assumption that the conjecture is correct, they obtained two classes of Boolean
Bifurcation of transversal homoclinics is studied for a pair of ordinary differential equations with periodic perturbations when the first unperturbed equa- tion has a manifold
A principal motivation for weakening the assumption of uniform expo- nential behavior is that from the point of view of ergodic theory, almost all linear variational equations in
On the tangent bundle of a Riemannian manifold (M, g) we consider a pseudo-Riemannian metric defined by a symmetric tensor field c on M and four real valued smooth functions defined
Our paper finds sufficient conditions for the curvature tensor (or the Ricci tensor) determines the Levi-Civita connection. On a Weyl manifold, we consider some special connections
We obtain necessary and sufficient conditions for the integrability of distributions on a semi-invariant submanifold and study the geometry of foliations defined by
Although the yields of grass and maize were on average lower than those on current farms, average farm yield is almost equal, because of a higher proportion of fodder beets and maize
