A Characterization of Signed Graphs with Generalized Perfect Elimination Orderings
Koji Nuida
An important property of chordal graphs is that these graphs are characterized by existence of perfect elimination orderings on their vertex sets. In this paper, we generalize the…

Signed-eliminable graphs and free multiplicities on the braid arrangement
Takuro Abe, Koji Nuida, Yasuhide Numata
We define specific multiplicities on the braid arrangement by using edge-bicolored graphs. To consider their freeness, we introduce the notion of bicolor-eliminable graphs as a gen…
