In this section we shall review some aspects of higher dimensional gravity, the construction of the so-called Maxwell algebra types, and obtaining odd- and even-dimensional general relativity from Chern–Simons gravity theory and from Born–Infeld theory, respectively. The main point of this section...

"Gauge Fields, Knots and Gravity" 由John Baez和Javier P. Muniain著。这本书用比较通俗的方式介绍了规范场理论、拓扑学和引力理论,可能更适合初学者。 Chern-Simons形式的定义 Chern-Simons形式是一种在纤维丛(特别是向量丛和主丛)上定义的微分形式。对于给定的联络(也就是规范场A)和其曲率(也就是场强F), ...
Another, more obvious and (only apparently) straightforward cure is the direct quantization of GR, along the canonical lines of loop quantum gravity [2, 3], for instance. The latter is based on a first order formulation of GR, which has two local symmetries: the invariances under the space...

Simons formulations of (2 +1)-dimensional gravity on M = [0, 1] ×T 2 . We now turn to the quantum theories. 2. Operators and Hilbert Spaces From now on, let us fix M to have the topology [0, 1] × T 2 . We begin with the sim- plest means of quantization, the Wheeler...
We use the transgression formula to find out a new fully covariant and global Lagrangian for Chern--Simons gravity: the price for establishing globality is hidden in a bimetric (or biconnection) structure. Such a formulation allows to calculate from a global and simpler viewpoint the energy-...
We have dealt so far with the possible ways in which pure gravity can be extended by relaxing three standard assumptions of General Relativity: Notion of parallelism derived from metricity, Four-di...
