Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
The bachelor thesis focuses on exploring the Hesse configuration, a geometric structure formed by the inflection points of an elliptic curve. The work aims to provide a detailed understanding of this configuration through two distinct approaches: a geometric approach using the Hesse pencil and an algebraic approach employing the group structure of elliptic curves.
- The Hesse configuration of nine points and twelve lines, its uniqueness and its realizations in different planes.
- The Hesse pencil, a linear system of cubic curves in the projective plane, and its role in defining the Hesse configuration.
- The group structure of elliptic curves and its connection to the Hesse configuration.
- The Cayleyan curve, a dual object to the Hesse configuration, and its construction through the theory of polar hypersurfaces.
- The Hessian group and its action on the Hesse pencil.
Zusammenfassung der Kapitel (Chapter Summaries)
The first part of the thesis delves into the Hesse configuration, presenting a geometric approach through the Hesse pencil. It examines the properties of the Hesse pencil and its relationship to the configuration, including the determination of a normal form for elliptic curves and the computation of the j-invariant. The second part explores the Hesse configuration from an algebraic perspective, leveraging the group structure of elliptic curves to understand the configuration's properties. This section also introduces the theory of polar hypersurfaces and its application to defining the Cayleyan curve, a dual object to the Hesse configuration.
