Anomaly cancellation for two factors
Ben Gripaios, Khoi Le Nguyen Nguyen
We show that solving the abelian part of the local anomaly cancellation conditions for a 4-d gauge theory whose gauge Lie algebra has an abelian summand with rank is equ…

Renormalized area of minimal surfaces in hyperbolic space
Matthew J. Gursky, Khoi Nguyen, Aaron J. Tyrrell
In this paper we consider minimal surfaces in hyperbolic space of arbitrary codimension that are critical for renormalized area. We give two criteria which imply that must be a…

The asymptotically-free gauge theories
Ben Gripaios, Khoi Le Nguyen Nguyen
We show how to classify the asymptotically-free gauge theories in four spacetime dimensions, focussing here on the case of purely fermionic matter. The classification depends on th…
