Index theory for actions of compact Lie groups on C*-algebras
Charlotte Wahl
We study the index theory for actions of compact Lie groups on C*-algebras with an emphasis on principal actions. Given an invariant semifinite trace on the C*-algebra we obtain se…

Homological index formulas for elliptic operators over C*-algebras
Charlotte Wahl
We prove index formulas for elliptic operators acting between sections of C*-vector bundles on a closed manifold. The formulas involve Karoubi's Chern character from K-theory of a…

Noncommutative Maslov Index and Eta Forms
Charlotte Wahl
We define and prove a noncommutative generalization of a formula relating the Maslov index of a triple of Lagrangian subspaces of a symplectic vector space to eta-invariants associ…
