Odd dimensional analogue of the Euler characteristic
L. Borsten, M. J. Duff, S. Nagy
When compact manifolds and are both even dimensional, their Euler characteristics obey the Künneth formula . In terms of the Betti numbers ,…
BRST-Lagrangian Double Copy of Yang-Mills Theory
Leron Borsten, Branislav Jurco, Hyungrok Kim +3
We show that the double copy of gauge theory amplitudes to supergravity amplitudes extends from tree level to loop level. We first explain that color-kinematic dual…
Black Holes and Higher Composition Laws
L. Borsten, M. J. Duff, A. Marrani
We describe various relations between Bhargava's higher composition laws, which generalise Gauss's original composition law on integral binary quadratic forms, and extremal black h…
Black holes and general Freudenthal transformations
L. Borsten, M. J. Duff, J. J. Fernández-Melgarejo +2
We study General Freudenthal Transformations (GFT) on black hole solutions in Einstein-Maxwell-Scalar (super)gravity theories with global symmetry of type . GFT can be conside…
Freudenthal duality and conformal isometries of extremal black holes
L. Borsten, M. J. Duff, A. Marrani
We present a conformal isometry for static extremal black hole solutions in all four-dimensional Einstein-Maxwell-scalar theories with electromagnetic duality groups `of type …
Twin conformal field theories
L. Borsten, M. J. Duff, A. Marrani
Supersymmetric theories with the same bosonic content but different fermions, aka \emph{twins}, were thought to exist only for supergravity. Here we show that pairs of super confor…
