This project explores the mathematics of surfaces and the many ways they can be deformed without tearing or gluing. Some surfaces are familiar, such as a sphere or a doughnut, while others are far more intricate, with infinitely many holes or directions to infinity. The goal is to understand these transformations and develop effective ways to describe and classify them. For simpler surfaces, classical theorems…
