场论中的几何结构

Geometric Structures in Field Theory

Manuel de León, Michael McLean, Larry K. Norris, Angel Rey-Roca, Modesto Salgado

摘要:

这篇评论文章关注的是推广到场论的切线和余切结构和束,发挥基本作用的拉格朗日和哈密顿公式的经典力学。本文回顾,比较和约束的各种概括,以带来一些统一的研究领域。概括起来似乎分为两类。在一个方向上,一些人推广了丛的几何结构,得到了各种公理系统,如k-辛和k-切结构。另一个方向是从根本上扩展束本身,然后探索扩展的自然几何形状。后一个方向给我们的多辛几何喷和cojet束和n-辛几何的框架束。

英文摘要:

This review paper is concerned with the generalizations to field theory of the tangent and cotangent structures and bundles that play fundamental roles in the Lagrangian and Hamiltonian formulations of classical mechanics. The paper reviews, compares and constrasts the various generalizations in order to bring some unity to the field of study. The generalizations seem to fall into two categories. In one direction some have generalized the geometric structures of the bundles, arriving at the various axiomatic systems such as k-symplectic and k-tangent structures. The other direction was to fundamentally extend the bundles themselves and to then explore the natural geometry of the extensions. This latter direction gives us the multisymplectic geometry on jet and cojet bundles and n-symplectic geometry on frame bundles.
