Sažetak

Let G be a metaplectic double cover of the group G of four-by-four real symplectic matrices.
Let $\frg$ be the complexified Lie algebra of G. Denote by $W_0$ and $W_1$ the Harish-Chandra modules of the even and odd Weil representations of $G$, respectively. We find the Dirac cohomology of $W_0$ and $W_1$ with respect to a noncompact Levi subalgebra $\frl$ of a $\theta$-stable parabolic subalgebra of $\frg$. The
results can be considered as counterexamples to certain generalizations of the main results of [9].
