How does a topologist classify the letters of the alphabet?

TL;DR

This paper explores topological classification of alphabet letters as subsets of the Euclidean plane using homeomorphisms, illustrating fundamental concepts in topology through a familiar example.

Contribution

It introduces a novel approach to teaching topology by classifying alphabet letters via homeomorphisms, connecting abstract concepts to visual and intuitive examples.

Findings

Letters can be classified into topological equivalence classes.

Homeomorphisms reveal fundamental shape similarities among alphabet letters.

The approach aids in understanding topological concepts through familiar objects.

Abstract

The paper approaches to the reader to topology with a curious example of topological classification by homeomorphisms applied to the letters of the alphabet viewed as subsets of Euclidean plane.
