Vol. 202 of Progress in Mathematics. Basel: Birkhäuser.http://nrs.harvard.edu/urn-3:HUL.InstRepos:3202704We give explicit equations for the simplest towers of Drinfeld modular curves over any finite field, and observe that they coincide with the asymptotically optimal towers of curves constructed by Garcia and Stichtenoth.en-US
