Sparsity Considerations in Dixon Resultants
New results relating the sparsity of nonhomogeneous polynomial systems and computation of their projection operator (a non-trivial multiple of the multivariate resultant) using Dixon's method are developed.

Extraneous Factors in the Dixon Resultant Formulation
Elimination methods based on generalizations of the Dixon's resultant formulation have been demonstrated to be efficient for simultaneously eliminating many variables from polynomials. One of these methods, presented by the authors earlier, was even

Solving Robust Glucose-Insulin Control by Dixon Resultant Computations [PDF]
We present a symbolic approach towards solving the Bergman three-state minimal patient model of glucose metabolism. Our work first translates the Bergman three-state minimal patient model into the modified control algebraic Riccati equation.

Algebraic and Geometric Reasoning using Dixon Resultants
Dixon's method for computing multivariate resultants by simultaneously eliminating many variables is reviewed. The method is found to be quite restrictive because often the Dixon matrix is singular, and the Dixon resultant vanishes identically ...

On the efficiency and optimality of Dixon-based resultant methods [PDF]
Structural conditions on polynomial systems are developed for which the Dixon-based resultant methods often compute exact resultants. For cases when this cannot be done, the degree of the extraneous factor in the projection operator computed using the Dixon-based methods is typically minimal.

Cayley-Dixon resultant matrices of multi-univariate composed polynomials
. The behavior of the Cayley-Dixon resultant construction and the structure of Dixon matrices are analyzed for composed polynomial systems constructed from a multivariate system in which each variable is substituted by a univariate polynomial in a ...

Resultants for unmixed bivariate polynomial systems produced using the Dixon formulation
A necessary and sufficient condition on the support of a generic unmixed bivariate polynomial system is identified such that for polynomial systems with such support, the Dixon resultant formulation produces their resultants.

Checking RSC criteria for extended Dixon resultant by interpolation method
Dixon resultant method can eliminate many variables simultaneously. It is often used to solve a system of polynomial equations. However, the Dixon matrix is often singular, and the Dixon resultant vanishes identically yielding no information about solutions for many algebraic and geometry problems.
