Center node: "achieving new upper bounds for the hypergraph duality problem through logic"
  Abstract: The hypergraph duality problem Dual is defined as follows: given two simple hypergraphs $\mathcal{G}$ and $\mathcal{H}$, decide whether $\mathcal{H}$ consists precisely of all minimal transversals of $\mathcal{G}$ (in which case we say that $\mathcal{G}$ is the dual of $\mathcal{H}$ or, equivalently, the transversal hypergraph of $\mathcal{H}$). This problem is equivalent to deciding whether two given nonredundant monotone disjunctive normal forms/conjunctive normal forms are dual. It is known that $\overline{{\sc Dual}}$, the complementary problem to Dual, is in GC($\log^2 n$, PTIME), where GC($f(n)$, $\mathcal{C}$) denotes the complexity class of all problems that after a nondeterministic guess of $O(f(n))$ bits can be decided (checked) within complexity class $\mathcal{C}$. It was conjectured that $\overline{{\sc Dual}}$ is in GC($\log^2 n$, LOGSPACE). In this paper we prove this conjecture and actually place the $\overline{{\sc Dual}}$ problem into the complexity class GC($\log^2 n$, TC$^{0}$) which i...
