DescriptionLet V be a 6-dimensional complex vector space with an involution σ of trace 0, and let W Sym^2 V* be a generic 3-dimensional subspace of σ-invariant quadratic forms. To these data we can associate an Enriques surface as the σ-quotient of the complete intersection of the quadratic forms in W. We exhibit noncommutative Deligne-Mumford stacks together with Brauer classes whose derived categories are equivalent to those of the Enriques surfaces.
