Query: On the characteristic $p$ valued measure associated to Drinfeld
  discriminant   In this paper, after reviewing known results on functions over Bruhat-Tits
trees and the theory of characteristic $p$ valued modular forms, we present
some structure of the tempered distributions on the projective space
${\P1}(\bk_\infty)$ over a complete function field $\bk_\infty$ of
characteristic $p$, and calculate the characteristic $p$ valued measure
associated to the Drinfeld discriminant and the characteristic $p$ valued
measure associated to the Poinca\'e series.
