On Kazama-Suzuki Duality between ${\mathcal{W}}_k({\mathfrak{sl}}_4,f_{\mathrm{sub}})$ and $N=2$ Superconformal Vertex Algebra

Dražen Adamović, Ana Kontrec

We classify all possible occurrences of Kazama-Suzuki duality between the $N=2$ superconformal algebra $L_c^{N=2}$ and the subregular $\mathcal{W}$-algebra $\mathcal{W}_{k}(\math…
