Nowadays curvature conditions are one of the powerful tools to study the geometry of Riemannian manifolds. In particular cases one can obtain geometric properties of a manifold from the curvature operator and its derivatives or vice versa. Now through this notes we w... Lees meer.

This monograph is based on the author s results on the Riemannian ge ometry of foliations with nonnegative mixed curvature and on the geometry of sub manifolds with generators rulings in a Riemannian space of nonnegative curvature. This monograph is based on the a... Lees meer.

This monograph explores applications of Carleman estimates in the study of stabilization and controllability properties of partial differential equations including quantified unique continuation logarithmic stabilization of the wave equation and null-controllability... Lees meer.

The central theme of this book is the theorem of Ambrose and Singer which gives for a connected complete and simply connected Riemannian manifold a necessary and sufficient condition for it to be homogeneous. This is a local condition which has to be satisfied at all... Lees meer.

This monograph deals with the Riemannian geometry of both symplectic and contact manifolds with particular emphasis on the latter. The text is carefully presented. Topics unfold systematically from Chapter 1 which examines the general theory of symplectic manifolds. P... Lees meer.

This work gives a coherent introduction to isoperimetric inequalities in Riemannian manifolds featuring many of the results obtained during the last 25 years and discussing different techniques in the area. Written in a clear and appealing style the book includes suff... Lees meer.

This is the third version of a book on differential manifolds. At the most basic level the book gives an introduction to the basic concepts which are used in differential topology differential geometry and differential equations. This is the third version of a boo... Lees meer.

Manifold optimization is an emerging field of contemporary optimization that constructs efficient and robust algorithms by exploiting the specific geometrical structure of the search space. In our case the search space takes the form of a manifold. Manifold optimization... Lees meer.

This book builds upon the revolutionary discovery made in 1974 that when one passes from function f to a function J of paths joining two points A1. A1 the connectivities R1 of the domain of f can be replaced by connectivities R1 over Q common to the pathwise components... Lees meer.

Towards the end of the nineteenth century Poincare developed methods for the study of global qualitative properties of solutions of dynamical systems in situations where explicit solution methods had failed. He discovered that the study of the geometry of the space o... Lees meer.

This monograph discusses covariant Schr dinger operators and their heat semigroups on noncompact Riemannian manifolds and aims to fill a gap in the literature given the fact that the existing literature on Schr dinger operators has mainly focused on scalar Schr dinger... Lees meer.

Stochastic analysis on Riemannian manifolds without boundary has been well established. However the analysis for reflecting diffusion processes and sub-elliptic diffusion processes is far from complete. This book contains recent advances in this direction along with n... Lees meer.
