Research
This page is devoted to my research in pure mathematics
(geometry and topology). My papers on natural language processing and
minority languages can be found
here.
Areas of Interest
- Hyperbolic, conformal, and Lorentzian geometry
- Deformations and rigidity of geometric structures
- Low-dimensional topology
