Positivity of the Gillis-Reznick-Zeilberger rational function

In this note we provide further evidence for a conjecture of Gillis, Reznick, and Zeilberger on the positivity of the diagonal coefficients of a multivariate rational function. Kauers had proven this conjecture for up to 6 variables using computer algebra. We present a variation of his approach that allows us to prove positivity of the coefficients up to 17 variables using symbolic computation.

Research Interest:-Cancer Biology The goal of our research effort is to understand the biology of cancer cells. From an understanding of the defects in a cancer cell, rational strategies for treatment can be developed.

David Smyth is a plant developmental geneticist. He began his independent career at Monash University in Melbourne in 1974, where he investigated the basis of the very large genomes of the true lilies (Lilium species) when DNA cloning methods became available. Two abundant dispersed elements turned out to be retrotransposons, revealing their important role in bulking up some plant genomes. In 1...

He uses this full breadth of computational methodologies far more ...
