DESCRIPTION:In general the restriction of an irreducible respresentation t
 o a subgroup is not irreducible. There are though cases where the restrict
 ion is irreducible. In this talk I will present a classification of irredu
 cible restrictions of representations of symmetric and alternating groups\
 , in particular about recent work joint with Alexander Kleshchev and Pham 
 Huu Tiep\, which\, up to one new family of irreducible restrictions\, exte
 nds to characteristics 2 and 3 the classification in larger characteristic
 \, up to considering also irreducible restrictions of spin representations
  when working in characteristic 2.  <br><br><br><br><br>
