# The geometric field of linearity of linear sets

@inproceedings{Jena2021TheGF, title={The geometric field of linearity of linear sets}, author={Dibyayoti Jena and Geertrui Van de Voorde}, year={2021} }

If an Fq-linear set LU in a projective space is defined by a vector subspace U which is linear over a proper superfield of Fq, then all of its points have weight at least 2. It is known that the converse of this statement holds for linear sets of rank h in PG(1, q) but for linear sets of rank k < h, the converse of this statement is in general no longer true. The first part of this paper studies the relation between the weights of points and the size of a linear set, and introduces the concept… Expand

The minimum possible size of an Fq-linear set of rank k in PG(1, q^n) is determined by relating it to the number of directions determined by a linearized polynomial whose domain is restricted to a subspace. Expand
