(Generalized) Spine Subalgebras of Fourier-Stieltjes algebras and their Homomorphisms

Nico Spronk, Ross Stokke, Aasaimani Thamizhazhagan

For any upper semilattice of locally precompact topologies on a locally compact group , we define an associated generalized spine subalgebra of the…

On operator Connes-amenability of the Fourier-Stieltjes algebra

Volker Runde, Nico Spronk, Matthew Wiersma

Runde and Spronk showed in 2004 that there are non-amenable groups , including , {whose Fourier-Stieltjes algebra, ,} is operator Connes-amenable. This result…

On - dichotomy for flat symmetric spaces

Sanjeev Kumar Gupta, Nico Spronk

For rank 1 flat symmetric spaces, continuous orbital measures admit absolutely continuous convolution squares, except for Cartan type AI. Hence - dichotomy for these spac…

Traces on locally compact groups

Brian Forrest, Nico Spronk, Matthew Wiersma

We conduct a systematic study of traces on locally compact groups, in particular traces on their universal and reduced C*-algebras. We introduce the trace kernel, and examine its r…

Fixed points and limits of convolution powers of contractive quantum measures

Matthias Neufang, Pekka Salmi, Adam Skalski +1

We study fixed points of contractive convolution operators associated to contractive quantum measures on locally compact quantum groups. We characterise the existence of non-zero f…

Corrigendum: Similarity degree of Fourier algebras

Hun Hee Lee, Ebrahim Samei, Nico Spronk

We address two errors made in our paper arXiv:1511.03423. The most significant error is in Theorem 1.1. We repair this error, and show that the main result, Theorem 2.5 of arXiv:15…
