Homotopy category

The homotopy category is a fundamental concept in algebraic topology and homotopy theory that captures the idea of "homotopy equivalence" between topological spaces (or more generally, between objects in a category) in a categorical framework. To understand the homotopy category, we begin with the following components: 1. **Topological Spaces and Continuous Maps**: In topology, we often deal with spaces that can be continuously deformed into each other.
