Generalised Entanglement Entropies from Unit-Invariant Singular Value Decomposition

Pawel Caputa, Abhigyan Saha, Piotr Sułkowski

We introduce generalisations of von Neumann entanglement entropy that are invariant with respect to certain scale transformations. These constructions are based on the Unit-Invaria…

Quivers and BPS states in 3d and 4d

Piotr Kucharski, Pietro Longhi, Dmitry Noshchenko +2

We propose a symmetrization relation between BPS quivers encoding 4d $N = 2$ theories and symmetric quivers associated to 3d $N = 2$ theories. We analyse in detail…

Wild wall-crossing and symmetric quivers in 4d and 3d $N = 2$ field theories

Daniel Bryan, Piotr Sułkowski

We reformulate Kontsevich-Soibelman wall-crossing formulae for 4d $N = 2$ class $S$ theories and corresponding BPS quivers, including those of wild type, as ident…
