广义相对论哈密顿约束的一阶约化

Reduction to first order of the Hamiltonian Constraint of General Relativity

Daniel W. F. Alves

摘要:

本文提出了一种求解广义相对论约束的方法,首先将所有的几何对象表示为一组正交三元组和一个平坦的Weitzenbock联络,这取决于三元组和一个平坦的自旋联络。结果表明,哈密顿约束可以从二阶方程降为一阶方程。即使方程的阶数减少了,我们也没有得到任何额外的方程来通过这个过程求解。文中还提出了一种共形分解。

英文摘要:

In this work, a method for solving the constraints of general relativity is presented, where first all geometrical objects are written in terms of a set of orthonormal triads and a flat Weitzenbock connection, which depends on the triads and on a flat spin connection. It is shown that the hamiltonian constraint can be reduced from a second order equation to a first order one. Even though the order of the equation is reduced, we do not get any extra equations to solve by this procedure. A conformal decomposition is also presented.
