On the location of roots of independence polynomials
Brown J., Hickman C., Nowakowski R. Journal of Algebraic Combinatorics: An International Journal 19(3): 273-282, 2004. Type: Article
Brown, Hickman, and Nowakowski study the locations of roots of independence polynomials. They prove that the real roots of independence polynomials are dense in (∞, 0], while complex roots are dense in the set of complex numb...

Gröbner bases for complete uniform families
Hegedűs G., Rónyai L. Journal of Algebraic Combinatorics: An International Journal 17(2): 171-180, 2003. Type: Article
In this paper, the authors present a completely explicit description of reduced Gröbner bases of the ideal of polynomials, which vanish on the set of characteristic vectors of the family of all d element sub...

Symplectic shifted tableaux and deformations of Weyl’s denominator formula for sp(2n)
Hamel A., King R. Journal of Algebraic Combinatorics: An International Journal 16(3): 269-300, 2002. Type: Article
The denominator formula of Weyl expresses a certain product taken over the positive roots of a Lie algebra gl(n) as a sum taken over the elements of the corresponding Weyl group of the Lie algebra. Tokuyama [1] prov...

On Narrow Hexagonal Graphs with a 3-Homogeneous Suborbit
Perkel M., Praeger C., Weiss R. Journal of Algebraic Combinatorics: An International Journal 13(3): 257-273, 2001. Type: Article
A characterization of a class of graphs (called polygonal) with degree k and girth equal to six, which have a number of properties for automorphism groups on vertices, is provided in this paper. The scarcity of examp...

Quasi-Minuscule Quotients and Reduced Words for Reflections
Stembridge J. Journal of Algebraic Combinatorics: An International Journal 13(3): 275-293, 2001. Type: Article
Stembridge studies reduced expressions for reflections in Coxeter groups, with particular emphasis on the reflections on finite crystallographic groups. It is shown in proposition 2.4 that the number of reduced expressions for any ref...

Generating testing and analysis tools with Aria
Devanbu P., Rosenblum D. (ed), Wolf A. Journal of Algebraic Combinatorics: An International Journal 5(1): 42-62, 1996. Type: Article
Aria is an abstract semantic graph tool for building testing and analysis tools for C and C++. Aria provides front-end processing, abstract semantic graph generation, and abstract semantic graph traversal. It is built from a generic to...

Program integration for languages with procedure calls
Binkley D., Horwitz S., Reps T. Journal of Algebraic Combinatorics: An International Journal 4(1): 3-35, 1995. Type: Article
When two or more programmers independently change a program’s source code, the changes should be merged only if the program’s intended behavior is preserved. Source code control systems vary in the degree to which t...
