Drinfeld modular polynomials of level $T$

Florian Breuer, Mahefason Heriniaina Razafinjatovo

We investigate Drinfeld modular polynomials parametrizing $T$ -isogenies between Drinfeld $F_{q} [T]$ -modules of rank $r \geq 2$ . By providing an explicit classification of suc…

Heights and isogenies of Drinfeld modules

Florian Breuer, Fabien Pazuki, Mahefason Heriniaina Razafinjatovo

We provide explicit bounds on the difference of heights of isogenous Drinfeld modules. We derive a finiteness result in isogeny classes. In the rank 2 case, we also obtain an expli…
