DESCRIPTION:The most important open problem in the modular representation 
 theory of the symmetric group is finding the number and multiplicity of th
 e composition factors of the Specht modules. In characteristic 0 these are
  just the simple modules of FSn\, but in positive characteristic they may 
 no longer be simple. We will survey the rich interplay between representat
 ion theory and combinatorics of partitions with the goal to show our ongoi
 ng work in obtaining an upper bound for certain Specht modules. We will co
 njecture how to extend this to all Specht modules.
