Geometric topology - Wikipedia
In mathematics, geometric topology is the study of manifolds and maps between them, particularly embeddings of one manifold into another.

An Introduction to Geometric Topology - unipi.it
The aim of this book is to introduce the reader to an area of mathematics called geometric topology. The text should be suitable to a master or PhD student in mathematics interested in geometry, and more generally to any curious mathematician with a standard background in topology and analysis.

2012年4月7日 · Geometric topology is very much motivated by low-dimensional phenomena -- and the very notion of low-dimensional phenomena being special is due to the existence of a big tool called the Whitney Trick, which allows one to readily convert certain problems in manifold theory into (sometimes quite complicated) algebraic problems.

Geometry and topology - Wikipedia
In mathematics, geometry and topology is an umbrella term for the historically distinct disciplines of geometry and topology, as general frameworks allow both disciplines to be manipulated uniformly, most visibly in local to global theorems in Riemannian geometry, and results like the Gauss–Bonnet theorem and Chern–Weil theory.
