Abstract: Interferometric observations in the mid-infrared made studies of the central dusty tori of Active Galactic Nuclei (AGNs) possible and proved their existence in a number of nearby AGNs. Our first results on Centaurus A (NGC 5128) showed that nuclear dust also exists in the innermost parsec of this galaxy (Meisenheimer et al. ...

Summary of the research statement "Geometry of hyp ercomplex manifolds" Andrey Soldatenkov The research pro ject is devoted to the study of the geometry of hypercomplex manifolds. A smooth manifold is called hypercomplex if it is equipped with a triple of integrable almost-complex structures satisfying quaternionic relations. There exist many examples of such manifolds including hyperkЁ ahler manifolds, nilmanifolds, Lie groups with hypercomplex structures and others. ...
