Abstract
Can Boutet de Monvel's algebra on a compact manifold with boundary be obtained as the algebra ψ0(G) of pseudo differential operators on some Lie groupoid G? If it could, the kernel G of the principal symbol homomorphism would be isomorphic to the groupoid C*-algebra C*(G). While the answer to the above question remains open, we exhibit in this paper a groupoid G such that C*(G) possesses an ideal I isomorphic to G. In fact, we prove first that G ≃ψ⊗ Κwith the Cz.ast;-algebra ψ generated by the zero order pseudo differential operators on the boundary and the algebra Κof compact operators. As both ψ Κ ⊗ Κ are extensions of C (S*Y) ψ ⊗ Κ by Κ(S*Y is the co-sphere bundle over the boundary) we infer from a theorem by Voiculescu that both are isomorphic. theory.
