DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OISTRTS/38/"
 >Young’s seminormal basis vectors and their denominators</a>\nby Kai Men
 g Tan (National University of Singapore) as part of OIST representation th
 eory seminar\n\n\nAbstract\nThe dual Specht module of the symmetric group 
 algebra over $\\mathbb{Q}$ has two distinguished bases\, namely the standa
 rd basis and Young’s seminormal basis. We study how the Young’s semino
 rmal basis vectors are expressed in terms of the standard basis\, as well 
 as the denominators of the coefficients in these expressions. We obtain cl
 osed formula for some Young’s seminormal basis vectors\, as well as part
 ial results for the denominators in general. This is a joint work with Min
 g Fang (Chinese Academy of Sciences) and Kay Jin Lim (Nanyang Technologica
 l University).\n
