Reduction of cocycles and groups of diffeomorphisms of the circle
We prove two theorems of reduction of cocycles taking values in the group of diffeomorphisms of the circle. They generalise previous results obtained by the author concerning rigidity for smooth actions on the circle of Kazhdan’s groups and higher rank lattices. Subject classification AMS (2000): primary 57S20; secondary 37A20.
متن کاملControllability on the Group of Diffeomorphisms
Given a compact manifold M , we prove that any bracket generating family of vector fields on M , which is invariant under multiplication by smooth functions, generates the connected component of the identity of the group of diffeomorphisms of M . Résumé Soit M une variété compacte, nous montrons que toute famille de champs de vecteurs satisfaisant la condition du rang et étant invariante par mu...
متن کاملHolonomies and Cohomology for Cocycles over Partially Hyperbolic Diffeomorphisms
We consider group-valued cocycles over a partially hyperbolic diffeomorphism which is accessible volume-preserving and center bunched. We study cocycles with values in the group of invertible continuous linear operators on a Banach space. We describe properties of holonomies for fiber bunched cocycles and establish their Hölder regularity. We also study cohomology of cocycles and its connection...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
