Résume

We discuss various notions of heights of Drinfeld modules and prove an explicit bound on the difference of heights of two isogenous Drinfeld modules. As applications, we give a new proof of the finiteness of isomorphism classes of Drinfeld modules over a global field in an isogeny class, as well as explicit bounds on the coefficients of Drinfeld modular polynomials in the case of rank r=2. (Joint work with Fabien Pazuki and Mahefason Heriniaina Razafinjatovo).
