Symplectic $\mathbb{Z}_2^n$-manifolds

Abstract: Roughly speaking, $\mathbb{Z}_2^n$-manifolds are manifolds' equipped with $\mathbb{Z}_2^n$-graded commutative coordinates with the sign rule being determined by the scalar product of their $\mathbb{Z}_2^n$-degrees. We examine the notion of a symplectic $\mathbb{Z}_2^n$-manifold, i.e., a $\mathbb{Z}_2^n$-manifold equipped with a symplectic two-form that may carry non-zero $\mathbb{Z}_2^n$-degree. We show that the basic notions and results of symplectic geometry generalise to thehigher graded' setting, including a generalisation of Darboux's theorem.
