Abstract

We construct a simply-connected compact complex non-K\"ahler manifold satisfying the ˉ\partial\bar\partial-Lemma, and endowed with a balanced metric. To this aim, we were initially aimed at investigating the stability of the property of satisfying the ˉ\partial\bar\partial-Lemma under modifications of compact complex manifolds and orbifolds. This question has been recently addressed and answered in \cite{rao-yang-yang, yang-yang, stelzig-blowup, stelzig-doublecomplex} with different techniques. Here, we provide a different approach using \v{C}ech cohomology theory to study the Dolbeault cohomology of the blow-up X~Z\tilde X_Z of a compact complex manifold XX along a submanifold ZZ admitting a holomorphically contractible neighbourhood.
