Complexities of Erez self-dual normal bases

Abstract

The complexities of self-dual normal bases, which are candidates for the lowest complexity basis of some defined extensions, are determined with the help of the number of all but the simple points in well chosen minimal Besicovitch arrangements. In this article, these values are first compared with the expected value of the number of all but the simple points in a minimal randomly selected Besicovitch arrangement in F d 2 for the first 370 prime numbers d. Then, particular minimal Besicovitch arrangements which share several geometrical properties with the arrangements considered to determine the complexity will be considered in two distinct cases.
