X ... Etc 5. Let u = (M1, . .., MK) be a partition. Recall that the conjugate partition u' was defined in two different ways in Lecture 10. Show that the two definitions of u' are equivalent: . u' is the partition whose diagram diag(u') is obtained from diag(u) by reflecting about the diagonal line from northwest to southeast, going through all the boxes labeled by (i, i). . N' = (M', . . ., H'"), where "; = [mi | mi > j -1}. X 21
