【Course Objectives】

Study cellular decomposition and homology groups of topological spaces as a means of perceiving the overall image of figures such as surfaces. Learn the Gauss–Bonnet theorem, which combines curvature, which is a local quantity with the Euler characteristic, which is a global quantity.

【Course Contents】

Geometry 1 used calculus to deal with the local theory of curves and surfaces, and studied curvature in detail. In Geometry 2, geodesic lines on surfaces are defined as a generalization of straight lines on a plane, and their properties are examined. Next we introduce the space form, which is characterized by the constant Gaussian curvature, and look at how Euclidean geometry is generalized. Then, after explaining the necessary facts about topological spaces, homology groups are defined and it is explained how they reflect a global aspect of shapes. After defining the Betti number and Euler’s characteristic using homology groups, the Gauss–Bonnet theorem is proven, which gives a relation between the curvature, a local quantity, with the Euler characteristic, a quantity defined from a global information.
