非拉格朗日引力理论的可能性

The Possibility of a Non-Lagrangian Theory of Gravity

Celia Escamilla-Rivera, Júlio C. Fabris

摘要:

广义相对论就像一个非常优雅的水晶玻璃:如果我们触摸它的原理,也就是它的拉格朗日,就有打破一切的危险。或者,如果我们愿意,它就像一条短毯子:解决一些问题会产生新的问题。本文旨在揭示我们为什么要在经典和量子物理基本原理的启发下,在原有的广义相对论的一个扩展假设下,追求一个非拉格朗日引力理论的可能性。

英文摘要:

General Relativity resembles a very elegant crystal glass: If we touch its principles, that is, its Lagrangian, there is a risk of breaking everything. Or, if we will, it is like a short blanket: Curing some problems creates new problems. This paper is devoted to bring to light the reasons why we pursue the possibility of a non-Lagrangian theory of gravity under the hypothesis of an extension of the original general relativity with an ansatz inspired in the fundamental principles of classical and quantum physics.
