Learning objectives
Develope a proper mathematical language.
Own abstract concept, theorems and proofs concerning differential topology.
Learn techniques to solve standard exercises and new problems, where the students need to elaborate a strategy similar to those seen in the lectures.
Prerequisites
Basic linear algebra, differential geometry, topology, and analysis.
Course unit content
Differential topology
