Abstract |
For the moduli space of Drinfeld modules, the compatification of Satake-Baily-Borel type was constructed by Kapranov in a special case and by Pink in general. The toroidal compactification was studied by Pink and Fujiwara in early 1990's and Pink wrote a short summary. However details were not yet published. Fukaya, Sharifi and I are completing a joint paper which describes the constructions of toroidal compactifications in detail. I will explain it. Polyhedral enlargements of Bruhat-Tits buildings play important roles there. |
