Positivity properties for q-Schur algebras. [PDF]

open access: yes, 1997
We prove Du's positivity conjecture for the canonical basis of the q-Schur algebra, using elementary arguments and the positivity result for Lusztig's canonical basis for U+q(sln).

Some bounds on the coupon collector problem with universal coupon

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
We consider a generalization of the coupon collector problem with unequal probabilities, such that there are two additional coupons in the coupon set: one that speeds up the coupon collection process, and the one that slows it down.

Schur-Convexity of Two Types of One-Parameter Mean Values in Variables

open access: yesJournal of Inequalities and Applications, 2007
We establish Schur-convexities of two types of one-parameter mean values in variables. As applications, Schur-convexities of some well-known functions involving the complete elementary symmetric functions are obtained.
