Course description and aims

As a continuation of "Introduction to Geometry I" MTH.B211, the following items about surfaces in the Euclidean 3-space are introduced:
parametrized surface, the first fundamental form; the length, the angle, and the area, the second fundamental form, the principal curvatures, the Gaussian and mean curvatures, geodesics, the Gauss-Bonnet theorem, the fundamental theorem of surface theory.
This course is a succession of " Introduction to Geometry I" in 3Q.

Student learning outcomes

The students will learn the basic matters of differential geometry of surface in the Euclidean 3-space. In particular
(1) To understand that the parametrization of surfaces and a notion of quantities which do not depend on parameters.
(2) To know the relationship between the shape of surfaces and curvatures.
(3) To know examples of global properties and local properties of surfaces.
(4) To confirm the theories by calculations on concrete examples.

Keywords

Differential Geometry, Surfaces, Gaussian cruvature, Mean curvature, the Gauss-Bonnet theorem.

Competencies that will be developed
