Geometric topology | Homeomorphisms
In mathematics, the y-homeomorphism, or crosscap slide, is a special type of auto-homeomorphism in non-orientable surfaces. It can be constructed by sliding a Möbius band included on the surface around an essential 1-sided closed curve until the original position; thus it is necessary that the surfaces have genus greater than one. The projective plane has no y-homeomorphism. (Wikipedia).
What is the difference between convex and concave polygons
👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1

Homeomorphisms and Homotopy Equivalences [Henry Adams]
We give a brief introduction to homeomorphisms, homotopy equivalences, and the difference between them. These notions describe when two shapes are described to be "the same" to a topologist. his tutorial was contributed as part of the WinCompTop+AATRN Tutorial-a-thon in Spring 2021: https
