作为非完整几乎Kahler几何的Einstein引力、Lagrange-Finsler变量和形变量子化

Einstein Gravity as a Nonholonomic Almost Kahler Geometry, Lagrange-Finsler Variables, and Deformation Quantization

Sergiu I. Vacaru

摘要:

一个几何程序的阐述转换(伪)黎曼度量和连接到规范的几何对象(度量和非线性和线性连接)的有效拉格朗日,或芬斯勒,几何,在他们反过来,可以等价地表示为几乎Kahler空间。这使我们能够按照变形量子化的标准方法来制定量子引力的方法。这样的构造不是在切丛上进行的,就像在通常的芬斯勒几何中一样,而是在具有非完整分布的时空上进行的,这些分布定义了2+2分裂和相关的非线性连接结构。我们还展示了如何爱因斯坦方程可以重新定义的拉格朗日-芬斯勒变量和相应的几乎辛结构和编码成零度上同调系数的量子模型的爱因斯坦流形。

英文摘要:

A geometric procedure is elaborated for transforming (pseudo) Riemanian metrics and connections into canonical geometric objects (metric and nonlinear and linear connections) for effective Lagrange, or Finsler, geometries which, in their turn, can be equivalently represented as almost Kahler spaces. This allows us to formulate an approach to quantum gravity following standard methods of deformation quantization. Such constructions are performed not on tangent bundles, as in usual Finsler geometry, but on spacetimes enabled with nonholonomic distributions defining 2+2 splitting with associate nonlinear connection structure. We also show how the Einstein equations can be redefined in terms of Lagrange-Finsler variables and corresponding almost symplectic structures and encoded into the zero-degree cohomology coefficient for a quantum model of Einstein manifolds.
