引力理论中演化方程的核方法
The method of the kernel of the evolution equation in the gravity theory
摘要：
“协变扰动理论”的方法允许计算自旋黎曼流形上的演化方程的核。提出的有效作用的公理化定义将具有长度平方维数的通用尺度参数引入无量纲数学理论。这一几何结果具有包括引力在内的场论作用的物理意义。在这个泛函中，张量秩的最低两阶与自旋群无关，并且是局部的。它们再现了相对论与宇宙学常数的作用。宇宙尺度的现代值可以通过测量的哈勃常数来确定。可变尺度参数可以让我们建立公理化的宇宙学理论。
英文摘要：
The method of 'covariant perturbation theory' allowed for the computation of the kernel of the evolution equation on a spin Riemannian manifold. The proposed axiomatic definition of the effective action introduces the universal scale parameter, with the length square dimensionality, into a dimensionless mathematical theory. It is shown that this geometrical result has a physical meaning of the action of field theory, including gravity. Two orders lowest in a tensor rank in this functional are independent of a spin group and local. They reproduce the action of relativity with the cosmological constant. The modern value of the universal scale could be determined by the measured Hubble constant. The variable scale parameter could let us build axiomatic cosmological theories.
