On split exact sequences and KK-equivalences of amplified graph C*-algebras
Jesse Reimann, Sophie Emma Zegers
We give a general methodology for constructing split exact sequences of amplified graph C*-algebras with sinks. This in turn allows us to construct explicit KK-equivalences with $\…

On the best constants of Schur multipliers of second order divided difference functions
Martijn Caspers, Jesse Reimann
We give a new proof of the boundedness of bilinear Schur multipliers of second order divided difference functions, as obtained earlier by Potapov, Skripka and Sukochev in their pro…
