Difference Schemes for Differential Equations with a Polynomial Right-Hand Side, Defining Birational Correspondences

Mathematics
This paper explores the numerical intergator of ODE based on combination of Appelroth’s quadratization of dynamical systems with polynomial right-hand sides and Kahan’s discretization method.

A few generalizations of Kendall’s tau. Part II: Intrinsic meaning, properties, and computational aspects

Nonlinear Analysis
Continuing our investigation on generalizations of Kendall’s τ, started in Part I of the paper, here we elaborate on the intrinsic meaning and degree of such polynomial-type concordance measures, as well as present many examples of their computation. In

On the algebraic properties of difference approximations of Hamiltonian systems

Discrete and Continuous Models and Applied Computational Science
In this paper, we examine difference approximations for dynamic systems characterized by polynomial Hamiltonians, specifically focusing on cases where these approximations establish birational correspondences between the initial and final states of the ...

Three identities and a determinantal formula for differences between Bernoulli polynomials and numbers

Electronic Research Archive
In the paper, the authors simply review recent results of inequalities, monotonicity, signs of determinants, determinantal formulas, closed-form expressions, and identities of the Bernoulli numbers and polynomials, establish an identity involving the ...

Polynomials, Divided Differences, and Codes

Multivariate multiplicity codes (Kopparty, Saraf, and Yekhanin, J. ACM 2014) are linear codes where the codewords are described by evaluations of multivariate polynomials (with a degree bound) and their derivatives up to a fixed order, on a suitably chosen affine point set.
