Variation of Hodge Structure and tt* Geometry, University of Hamburg,  Winter Term 2017/2018

This is an advanced graduate course for master and phd students as well as researchers who are interested in complex algebraic-geometric structures which originate from the physics of supersymmetric theories. The course will discuss the variation of Hodge structure and the associated special Kähler geometry, it will then proceed to a generalization of special Kähler geometry known as the topological anti-topological fusion geometry or tt* geometry.

Prerequisites:
A good knowledge of complex geometry and familiarity with algebraic geometry are required. A background in physics of supersymmetric theories is beneficial for the course but not necessary.

Topics of the course:

  1. (1)  Intuition for variation of Hodge structure from elliptic curves

  2. (2)  Variation of Hodge structure

  3. (3)  Special Geometry

  4. (4)  ttgeometry

  5. (5)  Advanced topics, e. g. quantum cohomology, twistorial structure of ttequations, algebraic structure of ttequations, relation to Hitchin systems.

Logistics:

The course takes place on:
  • Thursdays, 12:15 - 13:45 in H3 (Geomatikum)
