On Rieffel's conjecture characterizing a deformed algebra as Heisenberg smooth operators

Rodrigo A. H. M. Cabral, Severino T. Melo

Let be a unital C-algebra and be the Hilbert -module defined as the completion of the -valued Schwartz function space $\mathcal{S}…

Differential Norms and Rieffel Algebras

Rodrigo A. H. M. Cabral, Michael Forger, Severino T. Melo

We develop criteria to guarantee uniqueness of the C-norm on a *-algebra . Nontrivial examples are provided by the noncommutative algebras of -valued…

-Theory of Boutet de Monvel algebras with classical SG-symbols on the half space

Pedro T. P. Lopes, Severino T. Melo

We compute the -groups of the -algebra of bounded operators generated by the Boutet de Monvel operators with classical SG-symbols of order (0,0) and type 0 on $\mathbb{R}…

The Chern-Connes Character for pseudodifferential operators on the sphere

David P. Dias, Severino T. Melo

We compute the Chern-Connes character (a map from the -theory of a C-algebra under the action of a Lie group to the cohomology of its Lie algebra) for the -norm closure…

Cordes characterization for pseudodifferential operators with symbols valued on a noncommutative C*-algebra

Severino T. Melo, Marcela I. Merklen

Given a separable unital C*-algebra A, let E denote the Banach-space completion of the A-valued Schwartz space on Rn with norm induced by the A-valued inner product $<f,g>=\int f(x…

C*-Algebra-valued-symbol pseudodifferential operators: abstract characterizations

Severino T. Melo, Marcela I. Merklen

Given a separable unital C*algebra , let denote the Hilbert module equal to the completion of the Schwartz space of rapidly decreasing smooth functions from to e…
