Constructing Higher Nonlinear Odd-Variable RSBFs With Optimal AI and Almost Optimal FAI

open access: yesIEEE Access, 2019
Rotation symmetric Boolean functions (RSBFs) are nowadays studied a lot because of its easy operations and good performance in cryptosystem. This paper constructs a new class of odd-variable RSBFs with optimal algebraic immunity (AI). The nonlinearity of

Flexible algebras of degree two [PDF]

open access: yesTransactions of the American Mathematical Society, 1972
All known examples of simple flexible power-associative algebras of degree two are either commutative or noncommutative Jordan. In this paper we construct an algebra which is partially stable but not commutative and not a noncommutative Jordan algebra. We then investigate the multiplicative structure of those algebras which are partially stable over an

On a class of invariant algebraic curves for Kukles systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper we give a new upper bound for the degree of a class of transversal to infinity invariant algebraic curves for polynomial Kukles systems of arbitrary degree.

Necessary and sufficient conditions for the existence of invariant algebraic curves

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We present a set of conditions enabling a polynomial system of ordinary differential equations in the plane to have invariant algebraic curves. These conditions are necessary and sufficient. Our main tools include factorizations over the field of Puiseux

Generic planar algebraic vector fields are disintegrated

open access: yes, 2020
In this article, we study model-theoretic properties of algebraic differential equations of order $2$, defined over constant differential fields. In particular, we show that the set of solutions of a general differential equation of order $2$ and of ...

The algebraic degree of semidefinite programming [PDF]

open access: yesMathematical Programming, 2008
Given a generic semidefinite program, specified by matrices with rational entries, each coordinate of its optimal solution is an algebraic number. We study the degree of the minimal polynomials of these algebraic numbers. Geometrically, this degree counts the critical points attained by a linear functional on a fixed rank locus in a linear space of ...
