On the genus of reducible surfaces and degenerations of surfaces
We deal with a reducible projective surface with so-called , which are a generalization of normal crossings. First we compute the of , i.e. the dimension of the vector space of global sections of the dualizing sheaf . Then we prove that, when is smoothable, i.e. when is the central fibre of a flat family parametrized by a disc, with smooth general fibre, then the -genus of the fibres of is constant.
