  "abstract": "Let π: \\mathcal X \\rightarrow Δbe a smooth proper family of compact complex manifolds such that the central fiber \\mathcal X_0 is Kähler. Then all the fibers close to 0 are Kähler and π is a weakly Kähler morphism, even if \\mathcal X is not a Kähler space. In this paper we show that if dim \\mathcal X_0 = 4 and K_{\\mathcal X_0} is nef, then K_{\\mathcal X_t} is nef for all t in a neighborhood of the origin.",
