Sažetak

We present a coset realization of the vertex operator algebra $V_L ^+$ with central charge $1$.
We investigate the vertex operator algebra $V_{\Z
\sqrt{2n}} ^+$ (resp. $V_{2\Z \sqrt{2n+1}} ^+$) as a vertex
subalgebra of $L_{D_n ^{(1)}}(\Lambda _0) \otimes L_{D_n
^{(1)}}(\Lambda _0)$ (resp. $L_{B_n ^{(1)}}(\Lambda _0) \otimes
L_{B_n ^{(1)}}(\Lambda _0)$). Our construction is based on the
boson-fermion correspondence and certain conformal embeddings.
