Derivative of the standard -adic -function associated with a Siegel form
arXiv:1603.00956 · doi:10.1090/tran/7138
Abstract
In this paper we construct a two variables -adic -function for the standard representation associated with a Hida family of parallel weight genus Siegel forms, using a method previously developed by Böcherer--Schmidt in one variable. When a form of weight is Steinberg at , a trivial zero appears and, using the method of Greenberg--Stevens, we calculate the first derivative of this -adic -function and show that it has the form predicted by a conjecture of Greenberg on trivial zeros.
