On the classification of semifield flocks
Advances in Mathematics, 2003 The main result of this paper is the following one: Let \({\mathcal F}\) be a flock of a quadratic cone over the field \(\text{GF}(g^n)\) associated with a semifield plane with kernel \(\text{GF}(q)\), and such that \(q\geq 4n^2- 8n+ 2\), then \({\mathcal F}\) is a linear flock (all planes of the flock contain a fixed line), or a Kantor-Knuth flock ...

On automorphisms of semifields and semifield planes
Sibirskie Elektronnye Matematicheskie Izvestiya, 2016 Изучается взаимосвязь полуполевой проективной плоскости и ее координатизирующего полуполя с использованием линейного пространства и регулярного множества. Установлен геометрический смысл инволюторного автоморфизма конечного полуполя, доказаны некоторые его свойства.

Discrete Mathematics, 1999 An algebraic system \(S\) with two binary operations (addition and multiplication) is called a semifield if the following axioms are fulfilled: 1. \((S;+)\) is a group with identity \(0\). 2. If \(a,b\in S\) and \(ab=0\) then \(a=0\) or \(b=0\). 3. If \(a,b,c\in S\) then \(a(b+c)=ab+ac\) and \((a+b)c=ac+bc\). 4.

Semifields and a theorem of Abhyankar [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2017 Abhyankar proved that every field of finite transcendence degree over $\mathbb{Q}$ or over a finite field is a homomorphic image of a subring of the ring of polynomials $\mathbb{Z}[T_1, \dots, T_n]$ (for some $n$ depending on the field). We conjecture that his result can not be substantially strengthened and show that our conjecture implies a well ...

Applied statistics in field and semi-field studies with bees
Julius-Kühn-Archiv, 2020 Field and semi-field studies are important tools in the ecotoxicological risk assessment of plant protection products for bees (honey bees, bumblebees and solitary bees).

Advanced Gut &Microbiome Research, Volume 2026, Issue 1, 2026.The avian gut microbiota constitutes a complex, multiphyla ecosystem that critically shapes host physiology, immune function, disease resistance, and antimicrobial resistance dynamics. Bacteria, archaea, fungi, and viruses collectively regulate nutrient metabolism, mucosal barrier integrity, and immunological maturation, whereas dysbiosis increases ...

From semifield flocks to the generalized translation dual of a semifield [PDF]
Innovations in Incidence Geometry: Algebraic, Topological and Combinatorial, 2017 The goal of this article is to present developments of Thas’ relationship between translation geneneralized quadrangles and symplectic semifield spreads. Finally we discuss some open problems.
