Dual Murnaghan-Nakayama rule for Hecke algebras in Type $A$

Naihuan Jing, Ning Liu, Yu Wu

Let $χ_{μ}^{λ}$ be the value of the irreducible character $χ^{λ}$ of the Hecke algebra of the symmetric group on the conjugacy class of type $μ$ . The usual Murnaghan-Nakayama rule provid…

Irreducible characters and bitrace for the $q$ -rook monoid

Naihuan Jing, Yu Wu, Ning Liu

This paper studies irreducible characters of the $q$ -rook monoid algebra $R_{n} (q)$ using the vertex algebraic method. Based on the Frobenius formula for $R_{n} (q)$ , a new iterative ch…
