Labeling regions in deformations of graphical arrangements
Gábor Hetyei
Combining Carver's variant of the Farkas' lemma with the Flow Decomposition Theorem we show that the regions of any deformation of a graphical arrangement may be bijectively labele…

New formulas for the Jones polynomial of a rational link
Yuanan Diao, Gábor Hetyei
We derive new formulas for the Jones polynomial and the Kauffman bracket polynomial of a rational link represented by a standard diagram that is not necessarily alternating. These…

The toric g-vector of nestohedra
Richard Ehrenborg, Gábor Hetyei, Gábor Hetyei +1
We show the entries of the toric g-vector of any dual simplicial polytope is a nonnegative integer linear combination of its gamma-vector entries. We give combinatorial interpretat…
