论文摘要
本文介绍了牛顿 - 适用于庞加莱不变的古典系统的持续位置。我们证明了基本系统的存在和唯一定理,该系统与著名的牛顿(量子)定理平行。我们还讨论并证明了牛顿(Newton)的几何解释 - 威格尔(Newton)的位置为“旋转中心”,这已经在1965年在量子背景下再次提出。
This paper deals with the Newton--Wigner position observable for Poincaré-invariant classical systems. We prove an existence and uniqueness theorem for elementary systems that parallels the well-known Newton--Wigner theorem in the quantum context. We also discuss and justify the geometric interpretation of the Newton--Wigner position as `centre of spin', already proposed by Fleming in 1965 again in the quantum context.
