un 2 00 4 Making the hyper – Kähler structure of N = 2 quantum string manifest
We show that the Lorentz covariant formulation of N = 2 string in a curved space reveals an explicit hyper–Kähler structure. Apart from the metric, the superconformal currents couple to a background two–form. By superconformal symmetry the latter is constrained to be holomorphic and covariantly constant and allows one to construct three complex structures obeying a (pseudo)quaternion algebra. P...

متن کاملKähler (& Hyper-kähler) Manifolds
These notes are based on two talks given at the Arithmetic & Algebraic Geometry Seminar of the Korteweg-de Vriesinstituut for mathematics of the Universiteit van Amsterdam. They are intended to give a short introduction to the theory of Kähler manifolds, with a slight focus of applicability to the subject of K3 surfaces. However, they also include other interesting results not related to K3 sur...
متن کاملExamples of Hyper - Kähler Connections with Torsion
The internal space of a N=4 supersymmetric model with Wess-Zumino term has a connection with totally skew-symmetric torsion and holonomy in Sp(n), i.e. a HKTconnection. We study the mathematical background of this type of connections and provide several examples to illustrate the theory.
