On composite abstract homogeneous polynomials [PDF]
We study the null-sets of composite abstract homogeneous polynomials obtained from a pair of abstract homogeneous polynomials defined on a vector space over an algebraically closed field of characteristic zero. First such study for ordinary polynomials in the complex plane was made by Szegö, Cohn, and Egerváry and Szegö’s theorem was later generalized ...

Problems on multivariate reliability polynomial
The original results include: (i) homogenization of a reliability polynomial; (ii) compact hypersurfaces attached to homogeneous polynomials; (iii) an affine diffeomorphism that preserves a reliability polynomial; (iv) duality of networks via a ...

New iterative codes for 𝓗-tensors and an application
New iterative codes for identifying 𝓗 -tensor are obtained. As an application, some sufficient conditions of the positive definiteness for an even-order real symmetric tensor, i.e., an even-degree homogeneous polynomial form are given.

A Dichotomy for First-Order Reducts of Unary Structures [PDF]
Many natural decision problems can be formulated as constraint satisfaction problems for reducts $\mathbb{A}$ of finitely bounded homogeneous structures. This class of problems is a large generalisation of the class of CSPs over finite domains. Our first

Weights induced by homogeneous polynomials [PDF]
Let \(B\) be the unit ball and \(S\) the unit sphere in \({\mathbb{C}}^ n\) \((n\geq 2)\). Let \(\sigma\) be the unique normalized rotation-invariant Borel measure on \(S\) and \(m\) the normalized area measure on \({\mathbb{C}}.\) We first prove that if \(\Lambda\) is a holomorphic homogeneous polynomial on \({\mathbb{C}}^ n \)normalized so that ...

A note on the integrability of exceptional potentials via polynomial bi-homogeneous potentials
This paper is concerned with the polynomial integrability of the two-dimensional Hamiltonian systems associated to complex homogeneous polynomial potentials of degree k of type $V_{k,l}=\alpha (q_2-i q_1)^l (q_2+iq_1)^{k-l}$ with $\alpha$ in C and l=0 ...

The Nearest Zero Eigenvector of a Weakly Symmetric Tensor from a Given Point
We begin with a degree m real homogeneous polynomial in n indeterminants and bound the distance from a given n-dimensional real vector to the real vanishing of the homogeneous polynomial.

On the growth of gap power series of homogeneous polynomials
Let $f$ be an entire functions $f\colon \mathbb{C}^{p}\to\mathbb{C}$, represented by power series of the form $$f(z)=\sum\limits_{k=0}^{+\infty} P_k(z), z\in\mathbb{C}^p$$ where $P_0(z)\equiv a_{0}\in\mathbb{C}$, $P_k(z)=\sum\limits_{\|n\|=\lambda_k ...

Rigid Polynomial Differential Systems with Homogeneous Nonlinearities
Planar differential systems whose angular velocity is constant are called rigid or uniform differential systems. The first rigid system goes back to the pendulum clock of Christiaan Huygens in 1656; since then, the interest for the rigid systems has been

Positive Semi-Definite and Sum of Squares Biquadratic Polynomials
Hilbert proved in 1888 that a positive semi-definite (PSD) homogeneous quartic polynomial of three variables always can be expressed as the sum of squares (SOS) of three quadratic polynomials, and a psd homogeneous quartic polynomial of four variables ...
