我演讲的主题是一类以分区A(A1 '. An)参数a,其可以被有效地视为位置。我是真实的号码。对于a的特定值,这些多项式”自然地”出现:(i)当a= 1时,它们是(直到标量因子)Schur函数sA(x
The subject of my talk is a class of polynomial symmetric functions indexed by partitions A(A1'.••, An) a parameter a, which may be regarded usefully) as a po s i t. Lve real number. For particular values of a these polynomials occur" in nature":(i) when a= 1 they are (up to a scalar factor) the Schur functions sA (x
