Worpitzky partitions for root systems and characteristic quasi-polynomials.
arXiv:1501.04955 (Jan 21, 2015).
Our joint project "Geometry and combinatorics of hyperplane arrangements
and related topics" with team in Pau
(JSPS-MAE Sakura Program) is approved. (Sep. 2014--Aug. 2016).
I am working in
- Hyperplane Arrangements:
I am interested in several aspects of hyperplane arrangements.
- algebro-geometric properties of logarithmic vector fields and
their combinatorial applications,
- minimal CW decompositions of the complement, and
I am interested in transcendency of integrations.
