Computing the Characteristic Polynomial of Threshold Graphs

open access: yesJournal of Graph Algorithms and Applications, 2014
We present an algorithm for constructing the characteristic polynomial of a threshold graph's adjacency matrix. The algorithm is based on a diagonalization procedure that is easy to describe.

Constructing Concise Characteristic Samples for Acceptors of Omega Regular Languages [PDF]

open access: yesLogical Methods in Computer Science
A characteristic sample for a language $L$ and a learning algorithm $\textbf{L}$ is a finite sample of words $T_L$ labeled by their membership in $L$ such that for any sample $T \supseteq T_L$ consistent with $L$, on input $T$ the learning algorithm ...

More connections between the matching polynomial and the chromatic polynomial

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
The connection between the matching polynomial and the chromatic polynomial for triangle-free graphs was revealed in the work of Farrell and Whitehead. We extend this result to all graph by mirroring the corresponding result of Godsil and Gutman for the ...

THE CHARACTERISTIC POLYNOMIAL OF A MULTIARRANGEMENT [PDF]

open access: yes, 2006
Given a multiarrangement of hyperplanes we define a series by sums of the Hilbert series of the derivation modules of the multiarrangement. This series turns out to be a polynomial.

Bifurcation of the roots of the characteristic polynomial and the destabilization paradox in friction induced oscillations [PDF]

open access: yesTheoretical and Applied Mechanics, 2007
Paradoxical effect of small dissipative and gyroscopic forces on the stability of a linear non-conservative system, which manifests itself through the unpredictable at first sight behavior of the critical non-conservative load, is studied.

Roots of Characteristic Polynomial Sequences in Iterative Block Cyclic Reductions

open access: yesMathematics, 2021
The block cyclic reduction method is a finite-step direct method used for solving linear systems with block tridiagonal coefficient matrices. It iteratively uses transformations to reduce the number of non-zero blocks in coefficient matrices.

Commuting row contractions with polynomial characteristic functions

open access: yes, 2021
A characteristic function is a special operator-valued analytic function defined on the open unit ball of C n associated with an n-tuple of commuting row contraction on some Hilbert space.

Solving Fuzzy Polynomial Equations Systems Using Wu’s Method [PDF]

open access: yesپژوهش‌های نظری و کاربردی هوش ماشینی
In this paper, we introduce a method grounded in Wu’s algorithm for determining real solutions of systems of fuzzy polynomial equations. We initially calculate the r-cuts of a fuzzy polynomial equations system and derive a parametric representation for ...

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.
