Linear groups that are the multiplicative groups of neofields

Anthony B. Evans

Wright State University

Abstract: A neofield $N$ is a set with two binary operations, addition and multiplication, for which $N$ is a loop under addition with identity $0$, the nonzero elements of $N$ form a group under multiplication, and both left and right distributive laws hold. Which finite groups can be the multiplicative groups of neofields? It is known that any finite abelian group can be the multiplicative group of a neofield, but few classes of finite nonabelian groups have been shown to be multiplicative groups of neofields. We will show that each of the groups $GL(n, q)$, $PGL(n, q)$, $SL(n, q)$, and $PSL(n, q)$, $q$ even, $q\ne2$, can be the multiplicative group of a neofield.

Keywords and phrases: neofield, linear group, orthomorphism, near orthomorphism.
