| Popis: | In a recent work \cite{Liu:2023gzf}, I proposed a method to challenge the calculations of genus-$g$, bulk $n$-point, $b$-boundary, $c$-crosscap functions with $x$ boundary operators $\mathcal{F}_{g,n,b,c}^{x}$ of two-dimensional conformal field theories (CFT$_2$) by expanding them as infinite linear combinations of genus-$g$, $(n+b+c)$-point bulk correlation functions. Applying free field resolutions of chiral modules is an effective method for obtaining infinite linear coefficients in the expansion. We review free field resolution conjectures of dominant irreducible $\widehat{g}_{k}$ highest-weight modules and higher-rank parafermionic $\widehat{g}_{k}/ \widehat{u(1)}^{r}$ modules \cite{Bouwknegt:1989xa, Bouwknegt:1990fb, Bouwknegt:1990wa}, and apply them to corresponding Ishibashi states.
