چکیده

A new construction is given of cyclic semifields of orders q2n, n odd, with kernel (left nucleus) Fqn and right and middle nuclei isomorphic to Fq2 , and the isotopism classes are determined. Furthermore, this construction is generalized to produce potentially new semifields of the same general type that are not isotopic to cyclic semifields. In particular, a new semifield plane of order 45 and new semifield planes of order 165 are constructed by this method.

A Generalization of Some Huang-Johnson Semifields

In [H. Huang, N.L. Johnson: Semifield planes of order 82, Discrete Math., 80 (1990)], the authors exhibited seven sporadic semifields of order 26, with left nucleus F23 and center F2. Following the notation of that paper, these examples are referred as the Huang–Johnson semifields of type II, III, IV , V , V I, V II and V III. In [N. L. Johnson, V. Jha, M. Biliotti: Handbook of Finite Translati...

Some notes on the characterization of two dimensional skew cyclic codes

‎‎A natural generalization of two dimensional cyclic code ($T{TDC}$) is two dimensional skew cyclic code‎. ‎It is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $R_n:=F[x,y;rho,theta]/_l$‎. ‎In this paper we characterize the left ideals of the ring $R_n$ with two methods and find the generator matrix for two dimensional s...

On Condition (E?P)

In this paper we introduce condition (E?P) a generalization of Conditions (E?), (E) and (P) of acts over monoids and will give a classification of monoids by comparing this condition of their (Rees factor) acts with other properties. We give also a criterion of cyclic acts to satisfy Condition (E?P).

Fq-pseudoreguli of PG(3, q3) and scattered semifields of order q6

In this paper, we study rank two semifields of order q that are of scattered type. The known examples of such semifields are some Knuth semifields, some Generalized Twisted Fields and the semifields recently constructed in [12] for q ≡ 1(mod 3). Here, we construct new infinite families of rank two scattered semifields for any q odd prime power, with q ≡ 1(mod 3); for any q = 2, such that h ≡ 1(...

Innovations in Incidence Geometry

In 1965 Knuth [4] showed that from a given finite semifield one can construct further semifields manipulating the corresponding cubical array, and obtain in total six semifields from the given one. In the case of a rank two commutative semifield (the semifields corresponding to a semifield flock) these semifields have been investigated in [1], providing a geometric connection between these six ...
