We propose definitions of hypercomplex analytic spaces and hypercomplex schemes. We show that such a hypercomplex space is canonically associated to the quotient of a hypercomplex manifold by a finite group action.

Proposition 2.3
Let $X$ be a weakly hypercomplex space with $\tilde{X}$, and $R_\zeta$, $\zeta\in {\mathbb{P}}^1$, be as in Definition hc-space. Then $\sigma({R_\zeta})=R_{-1/\bar{\zeta}}$, $\forall\zeta\in {\mathbb{P}}^1$. If $X$ is hypercomplex, then the intersection $L\cap X$ of any equivalence class $L$ of any
