1. Quaternionic Transgression in Hyperkähler Geometry
Abstract : It is known, that hyperkähler varieties being a special case of Riemann and Kähler manifolds, admit more symmetries. For this reason, all important structures possibly admit hyperkähler generalization. Some of these generalizations make a theme of this thesis. READ MORE

2. The Complex World of Superstrings : On Semichiral Sigma Models and N=(4,4) Supersymmetry
Abstract : Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. Analyzing the geometrical and topological properties of sigma models is necessary to understand the underlying structures of string theory. READ MORE
