A Two-Color Lift of the Shifted $t$ -Schur Measure

S. -J. Lee

At the specialization $t = - q$ , $q \geq 0$ , the shifted $t$ -Schur function associated with the modified odd Greaves--Jing--Zhu operator is $Q_{I^} » [X + q X]$ . Instead of merging the two alph…

A Shifted $t$ -Schur Weight from the Modified Odd Operator

S. -J. Lee

We study the one-time weight on strict partitions obtained from the modified odd Greaves--Jing--Zhu operator. The shifted $t$ -Schur functions generated by this operator are obtaine…

Transition Matrices between Shifted $t$ -Schur Bases and Cyclotomic Schur $Q$ -Positivity

S. -J. Lee

For a strict partition $I^»$ , let $Q_{I^} » (X; t) = Q_{I^} » [X - tX]$ be the shifted $t$ -Schur function arising from the modified Greaves--Jing--Zhu operator on the odd power-sum ring.…

Mixed Products of Modified Greaves--Jing--Zhu Operators

S. -J. Lee

Let $Y (z; t)$ be the modified Greaves--Jing--Zhu operator on the odd power-sum ring. We first point out that this operator can be obtained from the classical neutral operat…

A Modified Greaves--Jing--Zhu Operator and a Shifted $t$ -Gessel Formula

S. -J. Lee

The recent work of Greaves, Jing, and Zhu gives an operator construction for the $t$ -Schur functions and the $t$ -Schur measure. Motivated by their construction, we consider the sam…
