General topology, also known as point-set topology, is a branch of mathematics that studies the properties of topological spaces. These properties are preserved under continuous deformations, such as stretching and bending, but not tearing or gluing. What if we only assume T1
One unspoken value of Engelking is its systematic inclusion of . Where many authors prove a theorem and move on, Engelking asks: What if we drop the Hausdorff axiom? What if we only assume T1? The book is dotted with references to the famous book Counterexamples in Topology (Steen & Seebach), but Engelking integrates these cautionary tales directly into the theory.
