Partially Ordered Sets

Sponsored by SIAM Activity Group on Discrete Mathematics (Invited Minisymposium)

10:30 AM-12:30 PM
Room: Savannah 3

The speakers in this minisymposium will present recent results on partially ordered sets. They will touch on central themes in combinatorics, graph theory and theoretical computer science and relations with randomized algorithms, correlation, sorting, ramsey theory, extremal set theory, hamiltonian paths and cycles, planar and outerplanar graphs, graph and hypergraph coloring and database security.
