广义函数代数中的Lorentz几何

On Lorentz geometry in algebras of generalized functions

Eberhard Mayerhofer

摘要:

本文在J.F. Colombeau,并在此背景下建立了逆Cauchy-Schwarz不等式。作为应用,我们证明了Hawking和Ellis在《时空的大尺度结构》一书中提出的某些能量张量的一个优势能量条件。我们的工作是基于广义数环上有限维模中自由元的一个新的刻画。

英文摘要:

We introduce a concept of causality in the framework of generalized pseudo-Riemannian Geometry in the sense of J.F. Colombeau and establish the inverse Cauchy-Schwarz inequality in this context. As an application, we prove a dominant energy condition for some energy tensors as put forward in Hawking and Ellis's book "The large scale structure of space-time". Our work is based on a new characterization of free elements in finite dimensional modules over the ring of generalized numbers.
