A hypergraph ℋ ⊆ 2 V is called uniformly δ-sparse if for every nonempty subset X ⊆ V of vertices, the average degree of the sub-hypergraph of ℋ induced by X is at most δ. We show that there is a deterministic algorithm that, given a uniformly δ-sparse hypergraph ℋ, and a positive integer k, outputs k or all minimal transversals for ℋ in O(δ 1og(1 + k)polylog(δ|V|))-time using |V| O(log δ)k O(δ) processors. Equivalently, the algorithm can be used to compute in parallel k or all maximal independent sets for ℋ.
