How is a Chordal Graph like a Supersolvable Binary Matroid?
Raul Cordovil, David Forge, Sulamita Klein
Let G be a finite simple graph. From the pioneering work of R. P. Stanley it is known that the cycle matroid of G is supersolvable iff G is chordal (rigid): this is another way to…

A note on Tutte polynomials and Orlik-Solomon algebras
Raul Cordovil, David Forge
Let A be a (central) arrangement of hyperplanes in a finite dimension complex vector space V. Let M(A) be the dependence matroid determined by A. The Orlik-Solomon algebra OS(M) of…

Diagonal bases in Orlik-Solomon type algebras
Raul Cordovil, David Forge
To encode an important property of the "no broken circuit bases" of the Orlik-Solomon-Terao algebras, Andras Szenes has introduced a particular type of bases, the so called "diagon…
