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 of Drinfeld modular polynomials and Hecke images

Florian Breuer, Fabien Pazuki, Zhenlin Ran

We obtain explicit upper and lower bounds on the size of the coefficients of the Drinfeld modular polynomials $Φ_{N}$ for any monic $N \in F_{q} [t]$ . These polynomials vanish at…
