引力场的实场纯联络公式

A pure connection formulation with real fields for Gravity

J. E. Rosales-Quintero

摘要:

我们研究了一个$SO(1,3)$纯连接配方在四个维度的实值字段,Capovilla,戴尔和雅各布森复杂的自对偶方法的启发。通过考虑CMPR BF作用,同时考虑李代数$\mathfrak{so(1,3)}$的Cartan-Killing形式的更一般的类,并通过精化Lagrange乘子的结构,我们整合出度量变量以获得纯连接作用.一旦我们得到了这个作用量,我们就对拉格朗日乘子施加了某些限制,这样,运动方程就把我们引向一族无挠共形平坦的爱因斯坦流形,用两个数来参数化。最后,我们表明,通过适当的参数选择,自对偶空间(反)德西特可以得到。

英文摘要:

We study an $SO(1,3)$ pure connection formulation in four dimensions for real-valued fields, inspired by the Capovilla, Dell and Jacobson complex self-dual approach. By considering the CMPR BF action, also, taking into account a more general class of the Cartan-Killing form for the Lie algebra $\mathfrak{so(1,3)}$ and by refining the structure of the Lagrange multipliers, we integrate out the metric variables in order to obtain the pure connection action. Once we have obtained this action, we impose certain restrictions on the Lagrange multipliers, in such a way that the equations of motion led us to a family of torsionless conformally flat Einstein manifolds, parametrized by two numbers. Finally, we show that, by a suitable choice of parameters, that self-dual spaces (Anti-) De Sitter can be obtained.
