SO(4,1)约束BF理论的Hamilton分析

Hamiltonian analysis of SO(4,1) constrained BF theory

R. Durka, J. Kowalski-Glikman

摘要:

本文讨论SO(4,1)约束BF理论的正则分析.这个理论的作用量包含拓扑项,加上一项将规范对称性分解到洛伦兹子群SO(3,1)。这个理论的运动方程就是真空爱因斯坦方程。通过求解B场方程,我们发现这个理论的作用量不仅包含标准的爱因斯坦-嘉当项,而且还包含与伊米尔齐参数的倒数成比例的霍尔斯特项,以及拓扑不变量的组合。我们证明了SO(4,1)约束BF理论的约束结构与Holst公式中的引力结构完全相同。我们还简要讨论了量子化的理论。

英文摘要:

In this paper we discuss canonical analysis of SO(4,1) constrained BF theory. The action of this theory contains topological terms appended by a term that breaks the gauge symmetry down to the Lorentz subgroup SO(3,1). The equations of motion of this theory turn out to be the vacuum Einstein equations. By solving the B field equations one finds that the action of this theory contains not only the standard Einstein-Cartan term, but also the Holst term proportional to the inverse of the Immirzi parameter, as well as a combination of topological invariants. We show that the structure of the constraints of a SO(4,1) constrained BF theory is exactly that of gravity in Holst formulation. We also briefly discuss quantization of the theory.
