Gauge Gauge Gravity on Homogeneous Spaces using Tensor Convolutions
L. Borsten, I. Jubb, V. Makwana +1
A definition of a convolution of tensor fields on group manifolds is given, which is then generalised to generic homogeneous spaces. This is applied to the product of gauge fields…

The pure BRST Einstein-Hilbert Lagrangian from the double-copy to cubic order
L. Borsten, S. Nagy
We construct the pure gravity Becchi-Rouet-Stora-Tyutin (BRST) Einstein-Hilbert Lagrangian, to cubic order, using the BRST convolution product of two Yang-Mills theories, in conjun…

Gauge Gauge on Spheres
L. Borsten, I Jubb, V. Makwana +1
We introduce a convolution on a 2-sphere and use it to show that the linearised Becchi-Rouet-Stora-Tyutin transformations and gauge fixing conditions of Einstein-Hilbert gravity co…
