Let $N$ be a smooth manifold such that its tangent bundle admits a CYMH GT, and let $K\to S$ be a Lie algebroid bundle over a smooth manifold $S$ which also admits a CYMH GT. Set ……

The discussion concerns four-dimensional BF theory, which admits two distinct kinematic algebras leading to corresponding double-copy theories. These constructions can appear diffe…

Consider the higher-derivative disformal transformation … where $C$, $D$, and $E$ are functions of the scalar field $\chi$ and $X$, and the last term also depends on the metric thr…
