A web is a family of foliations. We consider classical 3-webs andtheir generalizations, called Veronese webs, introduced by Gelfand andZakharevich in connection to bi-Hamiltonian systems. We show how thegeometry of webs can be used in the context of Einstein-Weylstructures.

A curious property of near-horizon geometry

For every extremal black hole (in any dimension) there exists a well-defined notion of its near-horizon geometry. This concept has been investigated for some time already; however, it seems to have passed unnoticed that every near-horizon metric admits a foliation consisting entirely of Killing horizons. It is here that the research paths cross with an independent inquiry stemming from analysis of isolated horizons...
