Bordisms and unbounded -theory

Robin J. Deeley, Magnus Goffeng, Bram Mesland

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

The odd spectral localiser via asymptotic morphisms and quasi-projections

Yuezhao Li, Bram Mesland

We describe the index pairing between an odd K-theory class and an odd unbounded Kasparov module by a pair of quasi-projections, supported on a submodule obtained from a finite spe…

Comparison of Levi-Civita connections in noncommutative geometry

Alexander Flamant, Bram Mesland, Adam Rennie

We compare the constructions of Levi-Civita connections for noncommutative algebras developed in arXiv:1505.07330, arXiv:1809.06721, arXiv:2403.13735. The assumptions in these vari…

Ideal quantum metrics from fractional Laplacians

Dimitris Michail Gerontogiannis, Bram Mesland

We develop a novel framework for Monge--Kantorovič metrics using Schatten ideals and commutators of fractional Laplacians on Ahlfors regular spaces. Notably, for those metrics we d…

Theta correspondence via group C*-algebras

Magnus Goffeng, Bram Mesland, Mehmet Haluk Sengun

We prove that the well-known explicit construction of the local theta correspondence by Li has a simple interpretation in terms of group C*-algebras. In particular, we deduce that…

Adelic C*-correspondences and parabolic induction

Magnus Goffeng, Bram Mesland, Mehmet Haluk Sengun

In analogy with the construction of representations of adelic groups as restricted products of representations of local groups, we study restricted tensor products of Hilbert C*-mo…
