Abstract:

L. Redei has studied in a detailed way so-called "lacunary" polynomials over finite fields. One of the applications described is to investigate the number of values the difference quotient of a polynomial over a finite field can have. This result has a direct implication in the theory of blocking sets of finite Desarguesian projective planes, and this connection is the start of the use of "Redei-polynomials" in finite geometry. We will discuss some cases to explain the principle of using Redei-polynomials finite projective spaces and some particular generalized quadrangle. Then we discuss a problem on maximal partial ovoids, that has been partially solved using Redei-polynomials, but that can be expressed in terms of transitive subsets of the group SL(2,q).
