On the Bochner technique for singular distributions
Paul Popescu, Vladimir Rovenski, Sergey Stepanov
In this paper we continue our recent study of a manifold endowed with a singular or regular distribution, determined as the image of the tangent bundle under a smooth endomorphism,…
An integral formula for a pair of singular distributions
Paul Popescu, Vladimir Rovenski
The paper is devoted to differential geometry of singular distributions (i.e., of varying dimension) on a Riemannian manifold. Such distributions are defined as images of the tange…
Almost Lie Algebroids and Characteristic Classes
Marcela Popescu, Paul Popescu
Almost Lie algebroids are generalizations of Lie algebroids, when the Jacobiator is not necessary null. A simple example is given, for which a Lie algebroid bracket or a Courant bu…
Coeffective basic cohomologies of --contact and Sasakian manifolds
Cristian Ida, Paul Popescu
In this paper we define coeffective de Rham cohomology for basic forms on a --contact or Sasakian manifold and we discuss its relation with usually basic cohomology of .…
Holomorphic last multipliers on complex manifolds
Mircea Crasmareanu, Cristian Ida, Paul Popescu
The goal of this paper is to study the theory of last multipliers in the framework of complex manifolds with a fixed holomorphic volume form. The motivation of our study is based o…
Contact structures on Lie algebroids
Cristian Ida, Paul Popescu
In this paper we generalize the main notions from the geometry of (almost) contact manifolds in the category of Lie algebroids. Also, using the framework of generalized geometry, w…
