Abstract

In this thesis, we study singular pseudo-differential operators defined by groupoids
satisfying the Lauter-Nistor condition, by a method parallel to that of manifolds
with boundary and edge differential operators. The example of the Bruhat sphere
is studied in detail. In particular, we construct an extension to the calculus of
uniformly supported pseudo-differential operators that is analogous to the calculus
with bounds defined on manifolds with boundary. We derive a Fredholmness criterion
for operators on the Bruhat sphere, and prove that their parametrices up to compact
operators lie inside the extended calculus; we construct the heat kernel of perturbed
Laplacian operators; and prove an Atiyah-Singer type renormalized index formula
for perturbed Dirac operators on the Bruhat sphere using the heat kernel method.
