DESCRIPTION:This talk concerns certain homomorphisms that aris
e in the study of Galois cohomology with restricte
d ramification. Given a set S of primes of a numbe
r field containing all those above a given prime p
\, the S-reciprocity map is a homomorphism on S-un
its that interpolates values of a cup product with
those S-units. We will discuss the properties of
and connections between this and related homomorph
isms\, and study their application to Selmer group
s of reducible representations. Finally\, we will
explore a connection with a conjecture of the auth
or on the relationship between these maps for cycl
otomic fields and a modular two-variable p-adic L-
function\, taken modulo an Eisenstein ideal.
