Poincaré superalgebras and triple systems
Paul de Medeiros
We consider a class of Poincaré superalgebras for which the nested bracket of three supercharges is necessarily zero only in dimensions greater than three. In lower dimensions, we…
Rigid supersymmetry, conformal coupling and twistor spinors
Paul de Medeiros
We investigate the relationship between conformal and spin structure on lorentzian manifolds and see how their compatibility influences the formulation of rigid supersymmetric fiel…
Eulerian digraphs and toric Calabi-Yau varieties
Paul de Medeiros
We investigate the structure of a simple class of affine toric Calabi-Yau varieties that are defined from quiver representations based on finite eulerian directed graphs (digraphs)…
Half-BPS quotients in M-theory: ADE with a twist
Paul de Medeiros, José Figueroa-O'Farrill, Sunil Gadhia +1
We classify Freund-Rubin backgrounds of eleven-dimensional supergravity of the form AdS_4 x X^7 which are at least half BPS; equivalently, smooth quotients of the round 7-sphere by…
Metric 3-Lie algebras for unitary Bagger-Lambert theories
Paul de Medeiros, José Figueroa-O'Farrill, Elena Méndez-Escobar +1
We prove a structure theorem for finite-dimensional indefinite-signature metric 3-Lie algebras admitting a maximally isotropic centre. This algebraic condition indicates that all t…
On the Lie-algebraic origin of metric 3-algebras
Paul de Medeiros, José Figueroa-O'Farrill, Elena Méndez-Escobar +1
Since the pioneering work of Bagger-Lambert and Gustavsson, there has been a proliferation of three-dimensional superconformal Chern-Simons theories whose main ingredient is a metr…
