dc.description.abstractSi considera un caso particolare di 3-folds compatte M diffeomorfi alla somma connessa di n copie di $\textrm{S}^{3}\times\textrm{S}^{3}$. Se n $\geq$2 , la varietà non-K$\ddot{\textrm{a}}$hleriana M ha una struttura complessa con $c_{1}$=0. Si dimostra che non ci sono fibrati lineari non-banali su M e quindi si deduce che il fibrato tangente di M è stabile rispetto ad ogni metrica di Gaudochon. Dal teorema di Li e Yau si conclude che su M esiste una metrica di Hermite-Einstein.
dc.description.abstractWe consider a special case of compact 3-folds M which are diffeomorphic to the connected sum of n copies of $\textrm{S}^{3}\times\textrm{S}^{3}$. If n $\geq$2 , the non-K$\ddot{\textrm{a}}$hler manifold M has a complex structure with $c_{1}$=0. We prove that there are no non-trivial line bundles on M and hence we deduce that its tangent bundle is stable with respect to any Gauduchon metric. By a theorem of Li and Yau we conclude that there is an Hermitian-Einstein metric on M.
