|Title:||On zeros of the characteristic polynomial of matroids of bounded tree-width|
|Citation:||European Journal of Combinatorics, 60: pp. 10 - 20, (2017)|
|Abstract:||We develop some basic tools to work with representable matroids of bounded tree-width and use them to prove that, for any prime power qq and constant kk, the characteristic polynomial of any loopless, GF(q)GF(q)-representable matroid with tree-width kk has no real zero greater than qk−1qk−1.|
