Title: Verifying p-valuation of class numbers
Abstract: Certain areas of Iwasawa theory requires knowledge of only the 
p-part of the class group. Computing this unconditionally with the full class 
group algorithm is infeasible for all but the simplest number fields. In this 
talk I will present a p-adic algorithm for computing/verifying the p-valuation 
of class numbers of totally real abelian number fields. This is joint work with 
my supervisor Claus Fieker.
