On the minimal polynomial of a resolvent [PDF]

open access: yesLinear Algebra and its Applications, 1987
The connection between the minimal polynomial of an operator and the minimal polynomial of its resolvent is derived. An analogous result is obtained for the minimal polynomials of iterated resolvents.

Evaluating the Tutte Polynomial for Graphs of Bounded Tree-Width [PDF]

open access: yes, 1998
It is known that evaluating the Tutte polynomial, $T(G; x, y)$, of a graph, $G$, is $\#$P-hard at all but eight specific points and one specific curve of the $(x, y)$-plane.

Cointegration, Root Functions and Minimal Bases

open access: yesEconometrics, 2021
This paper discusses the notion of cointegrating space for linear processes integrated of any order. It first shows that the notions of (polynomial) cointegrating vectors and of root functions coincide.

Computing Minimal Polynomials of Matrices [PDF]

open access: yesLMS Journal of Computation and Mathematics, 2008
AbstractWe present and analyse a Monte-Carlo algorithm to compute the minimal polynomial of ann × nmatrix over a finite field that requiresO(n3) field operations andO(n) random vectors, and is well suited for successful practical implementation. The algorithm, and its complexity analysis, use standard algorithms for polynomial and matrix operations. We

Embedding of Unimodular Row Vectors

open access: yesMathematics, 2023
In this paper, we mainly study the embedding problem of unimodular row vectors, focusing on avoiding the identification of polynomial zeros. We investigate the existence of the minimal syzygy module of the ZLP polynomial matrix and demonstrate that the ...

Minimizing polynomial functions [PDF]

open access: yes, 2003
We compare algorithms for global optimization of polynomial functions in many variables. It is demonstrated that existing algebraic methods (Gröbner bases, resultants, homotopy methods) are dramatically outperformed by a relaxation technique, due to N.Z. Shor and the first author, which involves sums of squares and semidefinite programming.

Polynomial cubic splines with tension properties [PDF]

open access: yes, 2010
In this paper we present a new class of spline functions with tension properties. These splines are composed by polynomial cubic pieces and therefore are conformal to the standard, NURBS based CAD/CAM ...

Fully Distributed Robust Formation Flying Control of Drones Swarm Based on Minimal Virtual Leader Information

open access: yesDrones, 2022
This paper studies the robust formation flying problem for a swarm of drones, which are modeled as uncertain second order systems. By making use of minimal virtual leader information, a fully distributed robust control scheme is proposed, which includes ...
