  2. 1. Traces of Hecke operators on Drinfeld modular forms via point counts

    Author : Sjoerd De Vries; Jonas Bergström; Gunther Cornelissen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinfeld modules; Drinfeld modular forms; trace formula; Ramanujan bound; slopes; matematik; Mathematics;

    Abstract : In this licentiate thesis, we study the action of Hecke operators on Drinfeld cusp forms via the theory of crystals over function fields. The thesis contains one preliminary chapter, in which we recall some basic theory of Drinfeld modules and Drinfeld modular forms, as well as the Eichler-Shimura theory developed by Böckle. READ MORE
