Abstract
In this paper we are studying the geometry of orthonormal frame bundles over Riemannian manifolds, which are equipped, as submanifolds of the full frame bundles, by the induced Sasaki–Mok metric. All kinds of curvatures are calculated and many geometric results are proved. It seems that the geometry of the orthogonal frame bundles is much more interesting (and more “flexible”) than that of the general frame bundles studied earlier by L. A. Cordero and M. de León.

This paper concerns Floer homology for periodic orbits and for a Lagrangian intersection problem on the cotangent bundle T \* M of a compact orientable manifold M. The first result is a new L ∞ estimate for the solutions of the Floer equation, which allows us to deal with a larger-and more natural-c

In this paper, we study the stability of Gabor frames ϕ mb na m n ∈ Z . We show that ϕ mb na m n ∈ Z remains a frame under a small perturbation of ϕ m, or n. Our results improve some results from Favier and Zalik and are applicable to many frequently used Gabor frames. In particular, we study the ca
