A TABLEAU FORMULA FOR ETA POLYNOMIALS
ETA POLYNOMIALS Differential and integral calculus
font style='font-size:12px;'>
2015/12/17
We use the Pieri and Giambelli formulas of [BKT1, BKT3] and
the calculus of raising operators developed in [BKT2, T1] to prove a tableau
formula for the eta polynomials of [BKT3] and the Stanley sym...

2015/12/17
We use Young’s raising operators to introduce and study double
eta polynomials, which are an even orthogonal analogue of Wilson’s double
theta polynomials. Our double eta polynomials give Giambelli ...
