Four-terminal reducibility and projective-planar wye-delta-wye-reducible graphs

- D. Archdeacon, C. Colbourn, I. Gitler, J. S. Provan
- Mathematics
- 1 February 2000

A graph is YΔY-reducible if it can be reduced to a vertex by a sequence of series-parallel reductions and YΔY-transformations. Terminals are distinguished vertices, that cannot be deleted by… Expand

Bounds For Invariants of Edge-Rings

- I. Gitler, C. E. Valencia
- Mathematics
- 1 April 2005

ABSTRACT Let G be a simple graph with |V(G)| = n and no isolated vertices. Let α be its stability number. We study invariants of the edge-ring of G that can be interpreted as invariants of G. If G… Expand

A Note on Rees Algebras and the MFMC Property

- I. Gitler, C. E. Valencia, R. Villarreal
- Mathematics
- 11 November 2005

We study irreducible representations of Rees cones and char- acterize the max-flow min-cut property of clutters in terms of the nor- mality of Rees algebras and the integrality of certain polyhedra.… Expand

- 21 September 2006

Let I = (x v 1 , . . . , x v q ) be a square-free monomial ideal of a polynomial ring K[x1, . . . , xn] over an arbitrary field K and let A be the incidence matrix with column vectors v1, . . . , vq.… Expand
