From: Michael Stone m-stone5 [snail] illinois.edu Mar 17 2012 Tableau symmetrizers are only "half orthogonal" =============================================== In appendix B you claim to have proof that for standard-tableau symmetrizers Y_a and Y_b, we have $Y_aY_b=Y_bYa= \delta_{ab} Y^2_a. What is usually said to be true, however, is that they are only "half orthogonal" In other words there is a total order on standard tableau of a given shape such that Y_aY_b=0 if a
