Title: Fun with Curves
ABSTRACT: In 1985, Jean-Pierre Serre gave a series of lectures at Harvard about the maximal number of
rational points on curves over finite fields. In my talk, I will tell about the motivations to study such
problem and, through 3 snapshots, show recent research directions.
Date and Time: Wednesday, September 22, 2021 (31 Shahrivar 1400)
16:30 - 17:30 (Tehran local time)

Title: Using Permutation Rational Functions to Obtain Permutation Arrays with Large Hamming Distance
ABSTRACT: We consider permutation rational functions (PRFs), V (x)/U(x), where both V (x) and U(x) are polynomials over a finite field Fq. Permutation rational functions have been the subject of several recent papers. Let M(n, D) denote the maximum number of permutations on n symbols with pairwise Hamming distance D. Computing lower bounds for M(n, D) is the subject of current research with applications in error correcting codes. Using PRFs of specified degrees d, we obtain improved lower bounds for M(q, q − k) for prime powers q and k ∈ {5, 6, 7, 8, 9}, and for M(q + 1, q − k) for prime powers q and k ∈ {4, 5, 6, 7, 8, 9}.
