There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The stable matching problem, first presented by mathematical economists Gale and Shapley, has been studied extensively since its introduction. As a result, a remarkably rich literature on the problem has accumulated in both theory and practice. We further extend our understanding on several algorithmic and structural aspects of stable matching. Our contributions can be summarized as follows:
- Generalizing stable matching to maximum weight stable matching.
- Finding stable matchings that are robust to shifts (a class of error introduced to the input).
- Generalizing Birkhoff's theorem for distributive lattices, and an application to robust stable matching on a larger class of error, namely permutations of any preference list of a boy or a girl.
The structural and algorithmic results introduced in this thesis naturally lead to a number of new questions. We believe that, considering the deep and pristine structure of stable matching, many of these questions do get settled satisfactorily.
