Letter L and Letter T are not Homeomorphic/Mistake

Source Work

 * $3$: Continuity generalized: topological spaces:
 * $3.6$: Homeomorphisms:
 * Examples $3.6.2 \ \text{(d)}$
 * Examples $3.6.2 \ \text{(d)}$

Mistake

 * The letter $\mathsf L$ and the letter $\mathsf T$ (defined as in $\text{(c)}$) are not homeomorphic.

Correction
The letter $\mathsf T$ is actually not defined in $\text{(c)}$.

In fact, nowhere in can a definition for the letter $\mathsf T$ actually be found.

The definition as provided on has been created from the viewpoint of an intuitive understanding of the material and a plausible interpretation.
