| contents | A five-dimensional minimal supergravity theory coupled to vector and hypermultiplets is specified by a set of trilinear couplings, given by an intersection form $C_{IJK}$, and gravitational couplings specified by an integer-valued vector $a_I$ and is consistent when these data define an integral cubic form. For every Calabi-Yau threefold reduction of M-theory, this condition is satisfied automatically. Via suitable redefinitions of the basis of 5D vectors, this is also shown to be the case for the circle reductions of six-dimensional anomaly-free (1,0) theories. When the 6D theory has a $\mathbb{Z}_k$ gauge symmetry, we point out that the consistency of the circle reduction with nontrivial $\mathbb{Z}_k$ holonomy is closely related to 6D constraints derived by Monnier and Moore. These constraints are extended to semidirect products with continuous gauge groups $\mathbb{Z}_k \ltimes G$ and CHL-like circle compactifications. When $\mathbb{Z}_k$ acts on anti-self-dual tensor fields of 6D supergravity, there should be a nontrivial action of holonomy on the topological Green-Schwarz terms. |
