Some Results on Inhomogeneous Discriminants
نویسنده
چکیده
We study generalized Horn-Kapranov rational parametrizations of inhomogeneous sparse discriminants from both a theoretical and an algorithmic perspective. We show that all these discriminantal parametrizations are birational, we prove some results on the corresponding implicit equations, and we propose a combinatorial algorithm to compute their degree in the uniform case of (co)dimension 3.

Parity of the number of irreducible factors for composite polynomials
Various results on parity of the number of irreducible factors of given polynomials over finite fields have been obtained in the recent literature. Those are mainly based on Swan’s theorem in which discriminants of polynomials over a finite field or the integral ring Z play an important role. In this paper we consider discriminants of the composition of some polynomials over finite fields. The ...
متن کاملStatistics of the Spectral Ratio and Log-likelihood Ratio Seismic Discriminants
The effect of noise variations on two of the short period seismic discriminants, spectral ratio and log-likelihood ratio is studied. The mean square errors of two different estimators of these two discriminants are evaluated and some theoretical and experimental results for two seismic signals in seismic noise are presented. Accepted for the Air Force Joseph R. Waterman, Lt. Col., USAF Chief, L...
متن کاملDistributions of Discriminants of Cubic Algebras Ii
Let k be a number field and O the ring of integers. In the previous paper [T06] we study the Dirichlet series counting discriminants of cubic algebras of O and derive some density theorems on distributions of the discriminants by using the theory of zeta functions of prehomogeneous vector spaces. In this paper we consider these objects under imposing finite number of splitting conditions at non...
متن کاملExplicit factors of some iterated resultants and discriminants
In this paper, the result of applying iterative univariate resultant constructions to multivariate polynomials is analyzed. We consider the input polynomials as generic polynomials of a given degree and exhibit explicit decompositions into irreducible factors of several constructions involving two times iterated univariate resultants and discriminants over the integer universal ring of coe cien...
متن کاملTorsion of cylindrically poroelasic circular shaft with radial inhomogeneity .some exact solutions for extruder
Torsion of elastic and poroelastic circular shaft of radially inhomogeneous, cylindrically orthotropic materials is studied with emphasis on the end effects example for extruder. To examine the conjecture of Saint-Venant’s torsion, we consider torsion of circular shaft with one end fixed and the other end free on which tractions that results in a pure torque are prescribed arbitrarily over the fr...
