Contents

• Surfaces in three-dimensional space, structure equations, first and second fundamental form, Gaussian and mean curvature,
• Examples of special surfaces (surfaces of revolution, ruled surfaces, minimal surfaces...), fundamental theorem of surface theory
• Basics of Riemannian geometry: Riemannian manifolds, connections and covariant derivatives, curvature tensor and derived curvature quantities, Einstein spaces, spaces of constant sectional curvature, geodesic curves, geodesic coordinates, exponential map, completeness properties (inner metric, theorem of Hopf-Rinow)
• physical applications of differential geometry, e.g. in special or general relativity theory

Qualification Goals

The students shall

• further develop their understanding of curved spaces and sharpen their mathematical intuition in a geometric context,
• learn to describe and xpress mathematical properties in a coordinate free way,
• learn to associate extremal geometric properties (such as curvature or curve length) with physical variation principles,
• practice mathematical working methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof techniques),
• improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.

Prerequisites

None. The competences taught in the following modules are recommended: either Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis, Complex Analysis and Vector Analysis.

Applicability

Module imported from M.Sc. Mathematics.

It can be attended at FB12 in study program(s)

• B.Sc. Mathematics
• M.Sc. Computer Science
• M.Sc. Mathematics
• LAaG Mathematics

When studying B.Sc. Mathematics, this module can be attended in the study area Compulsory Elective Modules in Mathematics.

Die Wahlmöglichkeit des Moduls ist dadurch beschränkt, dass es der Reinen Mathematics zugeordnet ist.
