DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OISTRTS/32/"
 >Spin representations of the symmetric group</a>\nby Dean Yates (Queen Mar
 y University of London) as part of OIST representation theory seminar\n\n\
 nAbstract\nSpin representations of the symmetric group S_n can be thought 
 of equivalently as either projective representations of S_n\, or as linear
  representations of a double cover S_n<sup>+</sup> of S_n. Whilst the line
 ar representation theory of S_n is dictated by removing ‘rim-hooks’ fr
 om (the Young diagrams of) partitions of n\, the projective representation
  theory of S_n is controlled by removing ‘bars’ from bar partitions of
  n (i.e. partitions of n into distinct parts). We will look at some combin
 atorial results on bar partitions from a recent paper of the author before
  discussing methods for determining the modular decomposition of spin repr
 esentations over fields of positive characteristic.\n
