Sažetak
We find all values of $k\in \Bbb C$, for which the embedding of the maximal affine vertex algebra in a simple minimal W- algebra $W_k( g, \theta)$ is conformal, where g is a basic simple Lie superalgebra and $-\theta$ its minimal root. In particular, it turns out that if $W_k(g, \theta)$ does not collapse to its affine part, then the possible values of these $k$ are either $-\frac{; ; ; ; ; ; ; ; ; 2}; ; ; ; ; ; ; ; ; {; ; ; ; ; ; ; ; ; 3}; ; ; ; ; ; ; ; ; h^\vee$ or $- \frac{; ; ; ; ; ; ; ; ; h^\vee- 1}; ; ; ; ; ; ; ; ; {; ; ; ; ; ; ; ; ; 2}; ; ; ; ; ; ; ; ; $, where $h^\vee$ is the dual Coxeter number of g for the normalization $(\theta, \theta)=2$. As an application of our results, we present a realization of simple affine vertex algebra $V_{; ; ; ; ; ; ; ; ; - \tfrac{; ; ; ; ; ; ; ; ; n+1}; ; ; ; ; ; ; ; ; {; ; ; ; ; ; ; ; ; 2}; ; ; ; ; ; ; ; ; }; ; ; ; ; ; ; ; ; (sl(n+1))$ inside the tensor product of the vertex algebra $W_{; ; ; ; ; ; ; ; ; \tfrac{; ; ; ; ; ; ; ; ; n-1}; ; ; ; ; ; ; ; ; {; ; ; ; ; ; ; ; ; 2}; ; ; ; ; ; ; ; ; }; ; ; ; ; ; ; ; ; (sl(2\vert n), \theta)$ (also called the Bershadsky-Knizhnik algebra) with a lattice vertex algebra.
