Abstract

Mathematics - Combinatorics Mathematics - Number Theory Mathematics - Rings and Algebras
We generalize and prove the recursive relation \[ S_(λ)(V) = _(L) V line S_(λ)(V /-5mu/ L) \] conjectured by I. G. Macdonald for his "7th variation" of the Schur functions. This variation is a family of polynomials over a finite field that mimic the (straight and skew) Schur polynomials using powers of the Frobenius.
