Spherical varieties and non-ordinary families of cohomology classes

Abstract: The theory of norm compatible cohomology classes is of fundamental importance in Iwasawa theory, encompassing both the theory of Euler systems and p-adic L-functions. Loeffler has developed a systematic approach to constructing norm-compatible classes using the theory of spherical varieties. We show that classes constructed in this way vary naturally in Coleman families and give some concrete applications.
