👉 A demorphism is a mathematical concept in category theory, which refers to a type of morphism between two categories that preserves all finite limits but reverses all infinite products. In other words, it's a kind of homotopy equivalence between two spaces or objects, where both are homotopically equivalent (i.e., they have the same homology groups) up to homotopies. Here is an example of a demorphism: 1. Let A be a category and F: AA
