Linear sparse differential resultant formulas

چکیده
Let P be a system of n linear nonhomogeneous generic sparse ordinary differential polynomials in n − 1 differential indeterminates. In this paper, differential resultant formulas are presented to compute, whenever it exists, the sparse differential resultant ∂Res(P) introduced by Li, Gao and Yuan in [12], as the determinant of the coefficient matrix of an appropriate set of derivatives of differential polynomials in P.

Macaulay Style Formulas for Sparse Resultants
We present formulas for computing the resultant of sparse polynomials as a quotient of two determinants, the denominator being a minor of the numerator. These formulas extend the original formulation given by Macaulay for homogeneous polynomials.
متن کاملSolving the Korteweg-de Vries Equation by Its Bilinear Form: Wronskian Solutions
Abstract. A broad set of sufficient conditions consisting of systems of linear partial differential equations is presented which guarantees that the Wronskian determinant solves the Korteweg-de Vries equation in the bilinear form. A systematical analysis is made for solving the resultant linear systems of second-order and third-order partial differential equations, along with solution formulas ...
متن کاملExact matrix formula for the unmixed resultant in three variables
We give the first exact determinantal formula for the resultant of an unmixed sparse system of four Laurent polynomials in three variables with arbitrary support. This follows earlier work by the author on exact formulas for bivariate systems and also uses the exterior algebra techniques of Eisenbud and Schreyer.
متن کاملMatrix Formulae of Differential Resultant for First Order Generic Ordinary Differential Polynomials
In this paper, a matrix representation for the differential resultant of two generic ordinary differential polynomials f1 and f2 in the differential indeterminate y with order one and arbitrary degree is given. That is, a non-singular matrix is constructed such that its determinant contains the differential resultant as a factor. Furthermore, the algebraic sparse resultant of f1, f2, δf1, δf2 t...
متن کاملA Circulant Preconditioner for the Systems of LMF-Based ODE Codes
In this paper, a recently introduced block circulant preconditioner for the linear systems of the codes for ordinary differential equations (ODEs) is investigated. Most ODE codes based on implicit formulas, at each integration step, need the solution of one or more unsymmetric linear systems that are often large and sparse. Here, the boundary value methods, a class of implicit methods for the n...
