时间反演算子的一般数学结构

A general mathematical structure for the time-reversal operator

Mario Alberto Castagnino, Adolfo Ramon Ordoniez, Daniela Beatriz Emmanuele

摘要:

这项工作的目的是数学分析的物理时间反演算子和它的定义作为一个几何结构\QTR{bf}{, }在这样一种方式,它可以推广到纯数学领域。严格地说,只有具有这样的“时间反演结构”,才能判定一个动力系统是否是时间对称的。\QTR{it} {\}给出了几个重要的物理和数学例子的“时间反演结构”,表明有一些数学范畴的对象是(经典的或抽象的)“时间反演系统”,它们的态射推广了Wigner变换。

英文摘要:

The aim of this work is the mathematical analysis of the physical time-reversal operator and its definition as a geometrical structure\QTR{bf}{, }in such a way that it could be generalized to the purely mathematical realm. Rigorously, only having such a ``time-reversal structure'' it can be decided whether a dynamical system is time-symmetric or not.\QTR{it}{\}The ``time-reversal structures'' of several important physical and mathematical examples are presented, showing that there are some mathematical categories whose objects are the (classical or abstract) ``time-reversal systems'' and whose morphisms generalize the Wigner transformation.
