DESCRIPTION:Title: Equivariant Iwasawa theory for Artin motives and applica
 tions\n	\n	Abstract:  Several years ago\, Greither and I formulated and gave
  a conditional proof  of an Equivariant Main Conjecture (EMC) in Iwasawa t
 heory for Artin motives over arbitrary global fields. We showed that\, via
  Iwasawa codescent\, this statement implies strong versions of the Brumer-
 Stark and Coates-Sinnott conjectures concerning special values of equivari
 ant  Artin L-functions at non-positive integers. \n	\n	In this lecture\, I w
 ill describe my recent joint work with Rusiru Gambheera\, in which we give
  unconditional proofs of two new versions of the EMC: one involving the Se
 lmer modules of Burns-Kurihara-Sano and the other involving the Ritter-Wei
 ss modules. I will then relate these results to my earlier work with Greit
 her and discuss their applications to proving various conjectures \n	on spe
 cial values of equivariant Artin L-functions. These advances rely cruciall
 y on the recent breakthrough results of Dasgupta and Kakde on Hilbert's tw
 elfth problem for totally real number fields.\n
