arXiv:2003.00955 · doi:10.1016/j.geomphys.2020.104036
Abstract
The purpose of this article is to present a "Groupoid proof" to the Lefschetz fixed point formula for elliptic complexes. We shall define a "relative version" of tangent groupoid, describe the corresponding pseudodifferential calculi and explain the relation with the Lefschetz fixed point formula.
