Finite semifields
This note surveys the known finite semifields and discusses the question: How many finite semifields of a given order are there up to isotopism?
متن کاملHarmonic semifields.
Communicated by S. S. Cherm, October 31, 1966 1. The solution of the principal field problem on arbitrary Riemannian spaces is given in reference 2. In the present note we consider the class S of harmonic semifields, intermediate between the class F of harmonic fields and the class H of harmonic forms. The definitions are as follows. On a given Riemannian space V let A' = 6d, A` = d6, A = A' + ...
متن کاملWhich elements of a finite group are non-vanishing?
Let $G$ be a finite group. An element $gin G$ is called non-vanishing, if for every irreducible complex character $chi$ of $G$, $chi(g)neq 0$. The bi-Cayley graph ${rm BCay}(G,T)$ of $G$ with respect to a subset $Tsubseteq G$, is an undirected graph with vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(tx,2)}mid xin G, tin T}$. Let ${rm nv}(G)$ be the set of all non-vanishi...
متن کاملMultilinear forms which are products of linear forms
The conditions under which, multilinear forms (the symmetric case and the non symmetric case),can be written as a product of linear forms, are considered. Also we generalize a result due to S.Kurepa for 2n-functionals in a group G.
متن کاملNew commutative semifields
We introduce infinite families of perfect nonlinear DembowskiOstrom multinomials over F p2k where p is any odd prime. We prove that for k odd and p 6= 3 these PN functions define new commutative semifields (in part by studying the nuclei of these semifields). This implies that these functions are CCZ-inequivalent to all previously known PN mappings.
