On the leading terms of zeta isomorphisms and pp-adic LL-functions in non-commutative Iwasawa theory

  • David Burns

We discuss the formalism of Iwasawa theory descent in the setting of the localized K1K_1-groups of Fukaya and Kato. We then prove interpolation formulas for the 'leading terms' of the global Zeta isomorphisms that are associated to certain Tate motives and of the pp-adic LL-functions that are associated to certain critical motives.
