Outline of Final Research Achievements |
I studied several topics on 3-dimensional topology and related algebra. Jointly with T. Widmer, I studied Kirby calculus for null-homotopic framed links and null-homologous framed links in 3-manifolds. Jointly with A. Beliakova, Z. Guliyev, A. D. Lauda, B. Webster and M. Zivkovic, I studied categorified quantum groups, in particular the ribbon element, the traces and the pivotal structure. Jointly with T. Q. T. Le, for each finite dimensional complex simple Lie algebra g, I constructed an invariant of integral homology 3-spheres which unify the quantum g invariants at various roots of unity.
