Project: Investigation of the action of arithmetical groups on the Bruhat-Tits tree in the function of gield case.

project duration
01-APR-99 – 30-SEP-99
In the investigations of the heights of Heegner points in the case of rational function fields, the action of arithmetical groups in characteristic p on the Bruhat-tits tree played an important role. We intend to study such actions of arithmetical groups also for general function fields (not necessarily rational function fields) and also the growth functions associated to these actions.
