Multiplicative chaos and the characteristic polynomial of the CUE: The 𝐿¹-phase [PDF]
In this article we prove that suitable positive powers of the absolute value of the characteristic polynomial of a Haar distributed random unitary matrix converge in law, as the size of the matrix tends to infinity, to a Gaussian multiplicative chaos ...

On Polynomial Values of the Discriminants of Characteristic Polynomials
For a square matrix \(A\), denote by \({\mathcal D} (A)\) the discriminant of its monic characteristic polynomial. Under some necessary conditions imposed on \(A\) and \(f\), \textit{J. G. Grytczuk} [Discuss. Math. 12, 45-51 (1992; Zbl 0787.11004)] showed that if \(A\) is a \(2\times 2\)-matrix with entries in \({\mathbb{Z}}\) and if \(f(X)\) is a ...

On the moments of the characteristic polynomial of a Ginibre random matrix [PDF]
In this article, we study the large N asymptotics of complex moments of the absolute value of the characteristic polynomial of an N×N complex Ginibre random matrix with the characteristic polynomial evaluated at a point in the unit disk.

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

On equiangular lines in 17 dimensions and the characteristic polynomial of a Seidel matrix [PDF]
For $e$ a positive integer, we find restrictions modulo $2^e$ on the coefficients of the characteristic polynomial $\chi_S(x)$ of a Seidel matrix $S$. We show that, for a Seidel matrix of order $n$ even (resp. odd), there are at most $2^{\binom{e-2}{2}}$

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

Roots of Characteristic Polynomial Sequences in Iterative Block Cyclic Reductions
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.

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