The group and the minimal polynomial of a graph
AbstractThis paper presents some results linking the minimal polynomial of the adjacency matrix of a graph with its group structure. An upper bound on the order of the group is derived for graphs whose minimal and characteristic polynomials are identical.

A standard form in (some) free fields: How to construct minimal linear representations
We describe a standard form for the elements in the universal field of fractions of free associative algebras (over a commutative field). It is a special version of the normal form provided by Cohn and Reutenauer and enables the use of linear algebra ...

A New Approach to Determine the Minimal Polynomials of Binary Modified de Bruijn Sequences
A binary modified de Bruijn sequence is an infinite and periodic binary sequence derived by removing a zero from the longest run of zeros in a binary de Bruijn sequence.

MINIMIZING POLYNOMIALS ON NONCOMPACT SETS
Summary: In this paper, the problem of minimizing a polymonial \(g_* = \inf\limits_{x \in S(F)}g(x)\) in the noncompact case is investigated. It is known that such problem is severely ill-posed. This paper studies the representation of a non-negative polynomial \(g\) on a noncompact semi-algebraic set \(S\) modulo its KKT (Karush-Kuhn-Tucker) ideal ...

Minimal Polynomials in Finite Semifields [PDF]
Summary: We consider the classical notion of a minimal polynomial and apply it to investigations in finite semifields. A proper finite semifield has non-associative multiplication, that leads to a number of anomalous properties of one-side-ordered minimal polynomials.

On the Structure of Valiant's Complexity Classes [PDF]
In Valiant developed an algebraic analogue of the theory of NP-completeness for computations of polynomials over a field. We further develop this theory in the spirit of structural complexity and obtain analogues of well-known results by Baker, Gill, and

Extremal Bicyclic Graphs with Respect to Permanental Sums and Hosoya Indices
Graph polynomials is one of the important research directions in mathematical chemistry. The coefficients of some graph polynomials, such as matching polynomial and permanental polynomial, are related to structural properties of graphs.

Vector-Valued Jack Polynomials from Scratch
Vector-valued Jack polynomials associated to the symmetric group S_N are polynomials with multiplicities in an irreducible module of S_N and which are simultaneous eigenfunctions of the Cherednik-Dunkl operators with some additional properties concerning
