The aim of this lecture course is to familiarize students with the basic language of, and some fundamental theorems in differential topology. This course will be succeeded by [MTH.B404 : Advanced topics in Geometry D].
As an outcome, students are expected to
・understand the notions of homotopy group, cobordism ring, the degree of a map etc.
・be familiar with the classification of surfaces, the method of smooth approximation, general position arguments, the chain complex for the homology group of a CW complex etc.
vector field, rotation, genus, homotopy group, degree, immersion, cobordism, transversality

They should do so by referring to textbooks and other course material.
