Center node: "stable matchings robust solutions and distributive lattices"
  Abstract: A stable matching instance $A$ is transmitted over a channel which introduces {\em one error} from a super-exponentially large set, $T$; the error consists of arbitrarily permuting the preference list of any one boy or any one girl. An arbitrary set $S \subseteq T$ is specified. We give an $O(|S| p(n))$ time algorithm for finding a matching that is stable for $A$ and for each of the $|S|$ instances that result by introducing one error from $S$, where $p$ is a polynomial function. In particular, if $S$ is polynomial sized, then our algorithm runs in polynomial time. Our algorithm is based on new, non-trivial structural properties of the lattice of stable matchings. #R##N#A second ingredient of our algorithm is a generalization of Birkhoff's Theorem for finite distributive lattices which states that corresponding to such a lattice, $\mathcal{L}$, there is a partial order, say $\Pi$, such that the lattice of closed sets of $\Pi$, $L(\Pi)$, is isomorphic to $\mathcal{L}$. Our generalization shows that corresponding to each sublattice $\mathcal{L}'$ of $\mathcal{L}$, there is a partial order $\Pi'$ that can be obtained from $\Pi$ (via a specified operation) such that $L(\Pi') \cong \mathcal{L}'$. This generalization is of independent interest.
