Monotonicity for Generalized Binomial Coefficients and Jack Positivity
Abstract.
Binomial formulas for Schur polynomials and Jack polynomials were studied by Lascoux in 1978, and Kaneko, Okounkov-Olshanski and Lassalle in the 1990s.
We prove that the associated binomial coefficients are monotone and derive some symmetric function inequalities, in particular, a Schur positivity and Jack positivity result.
These inequalities are similar to those studied by Newton, Muirhead, Gantmacher, Cuttler-Greene-Skandera, Sra and Khare-Tao.
