Some remarks on free products of rigid $C^{*}$ -2-categories

Matthias Valvekens

In this informal expository note, we present a universal, formulaic construction of the free product of rigid $C^{*}$ -2-categories. This construction allows for a straightforward, pu…

$L^{2}$ -Betti numbers of $C^{*}$ -tensor categories associated with totally disconnected groups

Matthias Valvekens

We prove that the $L^{2}$ -Betti numbers of a rigid $C^{*}$ -tensor category vanish in the presence of an almost-normal subcategory with vanishing $L^{2}$ -Betti numbers, generalising a res…
