摘要

In 1960 Hughes and Kleinfeld (Am J Math 82:389-392,1960) constructed a finite semifield which is two-dimensional over a weak nucleus, given an automorphism σ of a finite field K and elements μ, η ∈ K with the property that x~(σ+1) + μx - η has no roots in K. In 1965 Knuth (J Algebra 2:182-217, 1965) constructed a further three finite semifields which are also two-dimensional over a weak nucleus, given the same parameter set (K, σ, μ, η). Moreover, in the same article, Knuth describes operations that allow one to obtain up to six semifields from a given semifield. We show how these operations in fact relate these four finite semifields, for a fixed parameter set, and yield at most five non-isotopic semifields out of a possible 24. These five semifields form two sets of semifields, one of which consists of at most two non-isotopic semifields related by Knuth operations and the other of which consists of at most three non-isotopic semifields.
