The Fredholm index for operators of tensor product type
Karsten Bohlen
We consider bisingular pseudodifferential operators which are pseudodifferential operators of tensor product type. These operators are defined on the product manifold $M_1 \times M…

The K-theory of bisingular pseudodifferential algebras
Karsten Bohlen
In this paper we calculate the K-theory of -algebras given by the norm-closures of spaces of bisingular pseudodifferential operators. We obtain results for the \emph{glob…
