Main Body


1: Structured Description


Here is the rules of Structured Description.

Entities:
\( \mathbb{R}^d\): with the Euclidean metric
\(*O\): \(= \text{ the topology induced by the Euclidean metric }\)
//

Conditions:
//


2: Natural Language Description


For the Euclidean set, \(\mathbb{R}^d\), the topology induced by the Euclidean metric


3: Note


The Euclidean topological space, \(\mathbb{R}^d\), does not need to really have the Euclidean metric: the metric is used just in order to define the topology and the metric can be forgotten after that if one likes so. In fact, the topology can be defined without the metric, but this definition uses the metric in order to use the fact that the topology induced by any metric is indeed a topology.
