Proof that for any $u \in L_0$, there exists a $f(q) \in \mathbb{Q}[q]$ for which $f(q)u \in...
Setting
We consider subrings of $\mathbb{Q}(q)$:
$A_0$: localization at $(q)$
$A_{\infty}$: localization at $(q^{-1})$
$A$ = $\mathbb{Q}[q, q^{-1}]$
and free lattices of $\mathbb{Q}(q)$
$L_0$: …

About relation between Kostka numbers and Littlewood-Richardson coefficient
The fact that Kostka numbers equals to Littlewood-Richardson coefficients for some partitions is already known $\colon$
\begin{align}
K_{\lambda \mu} = c_{\sigma \lambda}^\tau
\end{align}
