| Abstract: | We study modular polynomials classifying cyclic isogenies between Drinfeld modules of arbitrary rank over the ring FqT]. We derive bounds for the coefficients of these polynomials, and compute some explicit examples in the case where q=2, the rank is 3 and the isogenies have degree T. |
