Boundary determination from local boundary data for a fractional Calderón problem

Heiko Gimperlein, Magnus Goffeng

We introduce a new Calderón-type problem for fractional powers of Schrödinger operators, with local boundary conditions. The associated Dirichlet-to-Neumann operator maps Dirichlet…

Five shades of KMS: Statistical properties in the spectral geometry of Cuntz--Krieger algebras

Dimitris Michail Gerontogiannis, Magnus Goffeng

We study spectral invariants arising in the noncommutative geometry of topological Markov chains and Cuntz--Krieger algebras. Their noncommutative geometry is described by spectral…

Bordisms and unbounded $K K$ -theory

Robin J. Deeley, Magnus Goffeng, Bram Mesland

This monograph studies $K K$ -theory in its unbounded model. The central object is the $K K$ -bordism group obtained by imposing the $K K$ -bordism relation on unbounded $K K$ -cycles. In…
