Main Body
1: Structured Description
Here is the rules of Structured Description.
Entities:
\(*T\): \(\in \{\text{ the topological spaces }\}\)
//
Conditions:
\(\exists f_c: T \to T, \in \{\text{ the constant maps }\}\)
(
\(id \simeq f_c\), where \(id\) is the identity map, \(id: T \to T\)
).
//
2: Natural Language Description
Any topological space, \(T\), on which the identity map, \(id: T \to T\), is homotopic to a constant map, \(f_c: T \to T\)
