A quadratic Poisson Gel'fand-Kirillov problem in prime characteristic [PDF]

open access: yes, 2015
The quadratic Poisson Gel’fand-Kirillov problem asks whether the field of fractions of a Poisson algebra is Poisson birationally equivalent to a Poisson affine space, i.e. to a polyno-mial algebra K[X1,..., Xn] with Poisson bracket defined by {Xi, Xj} =

Structural instability of friction-induced vibration by characteristic polynomial plane applied to brake squeal

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2020
Complex eigenvalue analysis has generally been applied to squeal improvement of automotive brake systems in recent years. Discrimination of the occurrence of unstable vibration by modal coupling has become common in brake design.

Gridding discretization-based multiple stability switching delay search algorithm: The movement of a human being on a controlled swaying bow. [PDF]

open access: yesPLoS ONE, 2017
Delay represents a significant phenomenon in the dynamics of many human-related systems-including biological ones. It has i.a. a decisive impact on system stability, and the study of this influence is often mathematically demanding. This paper presents a

图的Aα-特征多项式系数的一个注记(A note on the coefficients of the Aα-characteristic polynomial of a graph)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
Let G be a graph on n vertices, and let A( G ) and D ( G ) denote the adjacency matrix and the degree matrix of G, respectively. Define Aα ( G )= αD ( G )+( 1 - α ) A( G ) for any real α ∈ [ 0,1 ].

New polynomial-based molecular descriptors with low degeneracy. [PDF]

open access: yesPLoS ONE, 2010
In this paper, we introduce a novel graph polynomial called the 'information polynomial' of a graph. This graph polynomial can be derived by using a probability distribution of the vertex set.

Characteristic Polynomial and Eigenproblem of Triangular Matrix over Interval Min-Plus Algebra

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
A min-plus algebra is a linear algebra over the semiring R_ε', equipped with the operations “"⊕'=min" ” and “⊗=+”. In min-plus algebra, there is the concept of characteristic polynomial obtained from permanent of matrix.

ON ANTIADJACENCY MATRIX OF A DIGRAPH WITH DIRECTED DIGON(S)

open access: yesBarekeng, 2022
The antiadjacency matrix is one representation matrix of a digraph. In this paper, we find the determinant and the characteristic polynomial of the antiadjacency matrix of a digraph with directed digon(s).

Efficient computation of the characteristic polynomial of a threshold graph [PDF]

open access: yesTheoretical Computer Science, 2015
An efficient algorithm is presented to compute the characteristic polynomial of a threshold graph. Threshold graphs were introduced by Chvatal and Hammer, as well as by Henderson and Zalcstein in 1977.

Generalised characteristic polynomials

open access: yesJournal of Symbolic Computation, 1989
This paper is devoted to the extension of the classical elimination by resultant between two polynomials in one variable to the case of n polynomials in m variables with the coefficients in a field K. The key tool of the author's construction is the introduction of the generalized characteristic polynomial of the polynomials \(f_ 1,...,f_ n\).

On the characteristic polynomial of sl(2,F)

open access: yesLinear Algebra and its Applications, 2019
We prove Hu-Zhang's conjecture stated in [5] that the characteristic polynomial of a finite dimensional irreducible representation of sl ( 2 , F ) can be explicitly expressed as a product of some irreducible polynomials.
