Polynomial identities for partitions

open access: yesEuropean Journal of Combinatorics, 1992
Set \(P_ 1(q)=1-q\) and \(P_ k(q)=\sum_{d\mid k}\mu(k/d)\) for \(k>1\). For every integer \(m>1\) define \[ P^ +_{k,m}(q)=P_ k(q)(P_ k(q)+k)(P_ k(q)+2k)\cdots(P_ k(q)+(m-1)k), \] \[ P^ -_{k,m}(q)=P_ k(q)(P_ k(q)-k)(P_ k(q)-2k)\cdots(P_ k(q)-(m-1)k); \] and set \(P^ +_{k,0}(q)=P^ -_{k,0}(q)=1\).

MacWilliams Identities and Matroid Polynomials [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2002
We present generalisations of several MacWilliams type identities, including those by Kløve and Shiromoto, and of the theorems of Greene and Barg that describe how the Tutte polynomial of the vector matroid of a linear code determines the $r$th support weight enumerators of the code.

Annals of Combinatorics / Elementary polynomial identities involving q-trinomial coefficients [PDF]

open access: yes, 2019
We use the q-binomial theorem to prove three new polynomial identities involving q-trinomial coefficients. We then use summation formulas for the q-trinomial coefficients to convert our identities into another set of three polynomial identities, which imply ...

On the *-polynomial identities of M_{1;1}(E)

open access: yes, 2011
In this paper we consider the algebra M_{1,1}(E) endowed with the involution ∗ induced by the transposition superinvolution of the superalgebra M_{1,1}(F ) of 2 × 2-matrices over the field F . We study the ∗-polynomial identities for this algebra in the

Generalized monotone triangles [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
In a recent work, the combinatorial interpretation of the polynomial $\alpha (n; k_1,k_2,\ldots,k_n)$ counting the number of Monotone Triangles with bottom row $k_1 < k_2 < ⋯< k_n$ was extended to weakly decreasing sequences $k_1 ≥k_2 ≥⋯≥k_n$.

Generalized Pseudospectral Method and Zeros of Orthogonal Polynomials

open access: yesAdvances in Mathematical Physics, 2018
Via a generalization of the pseudospectral method for numerical solution of differential equations, a family of nonlinear algebraic identities satisfied by the zeros of a wide class of orthogonal polynomials is derived.

Irreducible polynomial identities in anticommutative algebras

open access: yes, 1970
The methods introduced by J. M. Osborn for isolating those polynomial identities worth studying in commutative algebras are here modified to yield three theorems for anticommutative algebras.

Homogeneous involution on graded division algebras and their polynomial identities

open access: yes, 2022
In this short note, we describe the so-called homogeneous involution on finite-dimensional graded-division algebra over an algebraically closed field. We also compute their graded polynomial identities with involution. As pointed out by L. Fonseca and T.

Attaching a matrix algebra to affine group schemes: Polynomial identities

open access: yes, 2023
We give a definition of polynomial identities for affine group schemes; over a field F of characteristic 0, the identities of an affine group scheme turn out to coincide with the identities of a certain matrix algebra over F.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
