Song of the Week: The Beach Boys - Good Vibrations

In the week Brian Wilson died this has to be Song of the Week. Brian, who featured in a previous Song of the Week with the anguished 'Still I Dream of It', wrote many great songs - and it's worth checking out all the obituaries which link to them if you don't know his work - but 'Good Vibrations' is the pinnacle.

Applications of Equivariant Localization in Supergravity

Christopher Couzens
(Oxford)
Abstract

Einstein’s equations are difficult to solve and if you want to compute something in holography knowing an explicit metric seems to be essential. Or is it? For some theories, observables, such as on-shell actions and free energies, are determined solely in terms of topological data, and an explicit metric is not needed. One of the key tools that has recently been used for this programme is equivariant localization, which gives a method of computing integrals on spaces with a symmetry. In this talk I will give a pedestrian introduction to equivariant localization before showing how it can be used to compute the on-shell action of 6d Romans Gauged supergravity.
