双仿射丛

Double Affine Bundles

Janusz Grabowski, Mikolaj Rotkiewicz, Pawel Urbanski

摘要:

作为双向量丛理论的仿射对应,发展了双仿射丛和特殊双仿射丛理论,即具有两个相容(特殊)仿射丛结构的微分流形.动机和基本的例子来自分析力学,其中双仿射丛已被认为是一个适当的几何工具,在一个独立的框架描述许多重要的系统。不同的方法(特殊)双仿射束进行了比较和仔细研究的问题,双向量丛模型和外壳,对偶性,以及相关的相空间,切触结构,和其他规范的建设。

英文摘要:

A theory of double affine and special double affine bundles, i.e. differential manifolds with two compatible (special) affine bundle structures, is developed as an affine counterpart of the theory of double vector bundles. The motivation and basic examples come from Analytical Mechanics, where double affine bundles have been recognized as a proper geometrical tool in a frame-independent description of many important systems. Different approaches to the (special) double affine bundles are compared and carefully studied together with the problems of double vector bundle models and hulls, duality, and relations to associated phase spaces, contact structures, and other canonical constructions.
