Natural vs. artificial topologies on a relativistic spacetime
K Papadopoulos - Nonlinear Analysis and Global Optimization, 2021 - Springer
Consider a set M equipped with a structure∗. We call a natural topology T∗, on (M,∗), the
topology induced by∗. For example, a natural topology for a metric space (X, d) is a topology …
