形状动态

Shape Dynamics

Tim Koslowski

摘要:

巴鲁德对马赫原理的表述需要一个引力理论来实现钟的局部相对性、杆的局部相对性和空间协变性。事实证明,钟和杆的相对性是相互排斥的。广义相对论实现了时钟和空间协方差的局部相对性,但没有实现棒的局部相对性。这是本贡献的目的,以显示如何形状动力学,一个理论,是当地相当于广义相对论,实现当地的相对性杆和空间协方差和如何一个BRST制定,我呼吁Doubly广义相对论,实现所有的Barthel的原则。

英文摘要:

Barbour's formulation of Mach's principle requires a theory of gravity to implement local relativity of clocks, local relativity of rods and spatial covariance. It turns out that relativity of clocks and rods are mutually exclusive. General Relativity implements local relativity of clocks and spatial covariance, but not local relativity of rods. It is the purpose of this contribution to show how Shape Dynamics, a theory that is locally equivalent to General Relativity, implements local relativity of rods and spatial covariance and how a BRST formulation, which I call Doubly General Relativity, implements all of Barbour's principles.
