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 algebraicgeometric 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 antitopological 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)
Intuition for variation of Hodge
structure from elliptic curves

(2)
Variation of Hodge structure

(3) Special
Geometry

(4) tt∗ geometry

(5) Advanced
topics, e. g. quantum cohomology,
twistorial structure of tt∗equations,
algebraic structure of tt∗ equations,
relation to Hitchin systems.
Logistics:
The
course takes place on:
 Thursdays, 12:15  13:45 in H3 (Geomatikum)
