DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OISTRTS/19/"
 >On the computation of decomposition numbers of the symmetric group</a>\nb
 y Diego Millan Berdasco (Queen Mary University of London) as part of OIST 
 representation theory seminar\n\n\nAbstract\nThe most important open probl
 em in the modular representation theory of the symmetric group is finding 
 the multiplicity of the simple modules as composition factors of the Spech
 t modules. In characteristic 0 the Specht modules are just the simple modu
 les of the symmetric group algebra\, but in positive characteristic they m
 ay no longer be simple. We will survey the rich interplay between represen
 tation theory and combinatorics of integer partitions\, review a number of
  results in the literature which allow us to compute composition series fo
 r certain infinite families of Specht modules from a finite subset of them
 \, and discuss the extension of these techniques to other Specht modules.\
