广义时间函数与洛伦兹距离的有限性
Generalised time functions and finiteness of the Lorentzian distance
摘要:
我们证明了洛伦兹距离的有限性等价于广义时间函数的存在性,广义时间函数的梯度均匀有界远离光锥。为了得出这一结果,我们引入新的技术来构建和操作的时间集。作为这些技术的结果,我们得到的洛伦兹距离扩展佛朗哥和莫雷蒂的工作的功能描述。
英文摘要:
We show that finiteness of the Lorentzian distance is equivalent to the existence of generalised time functions with gradient uniformly bounded away from light cones. To derive this result we introduce new techniques to construct and manipulate achronal sets. As a consequence of these techniques we obtain a functional description of the Lorentzian distance extending the work of Franco and Moretti.
