In the Iwasawa theory of padic Galois representations over
the cyclotomic tower, a key role is played by PerrinRiou’s regulator
or dual exponential map (particularly for nonordinary Galois
representations). I will describe a generalisation of this map to
Iwasawa theory for certain towers of extensions whose Galois groups
are abelian padic Lie groups of dimension 2, and some applications of
this construction to Galois representations arising from modular
forms. This is a joint project with Sarah Zerbes.
