A biparacomplex structure is an almost biparacomplex structure in the setting of the paper, and a functorial connection is a connection naturally attached to such a structure. Uniq…

Let $\varpi \in \bigwedge^{k+1}V^*$ be a multisymplectic structure of constant linear type on a smooth manifold. Its associated $G_\varpi$-structure has vanishing structure tensors…

A $G$-structure is formally flat if it satisfies the formal flatness conditions associated with its structure tensors, and it is flat if it is locally equivalent to a constant-coef…

Let $G \to \operatorname{GL}(n,\mathbb{C})$ be a representation with discrete kernel and closed image. Let $R$ be a torsion relation for $G$, and let $R'$ be the induced invariant…
