On a higher level extension of Leclerc-Thibon product theorem in q-deformed Fock spaces
Kazuto Iijima
The q-deformed Fock spaces of higher levels were introduced by Jimbo-Misra-Miwa-Okado. Uglov defined a canonical bases in q-deformed Fock spaces of higher levels. Leclerc-Thibon sh…

A -multinomial expansion of LLT coefficients and plethysm multiplicities
Kazuto Iijima
Lascoux, Leclerc and Thibon\cite{LLT} introduced a family of symmetric polynomials, called LLT polynomials. We prove a -multinomial expansion of the coefficients of LLT polynomi…

A comparison of q-decomposition numbers in the q-deformed Fock spaces of higher levels
Kazuto Iijima
The q-deformed Fock spaces of higher levels were introduced by Jimbo-Misra-Miwa-Okado. The q-decomposition matrix is a transition matrix from the standard basis to the canonical ba…
