In this paper we show that even in the case of simply connected minimal algebraic surfaces of general type, deformation and differentiable equivalence do not coincide. Exhibiting several simple families of surfaces which are not deformation equivalent, and proving their diffeomorphism, we give a counterexample to a weaker form of the speculation DEF = DIFF of R. Friedman and J. Morgan, i.e., in...

In the present paper we consider fibrations f : S → B of an algebraic surface onto a curve B, with general fibre a curve of genus g. Our main results are: 1) A structure theorem for such fibrations in the case g = 2 2) A structure theorem for such fibrations in the case g = 3 and general fibre nonhyperelliptic 3) A theorem giving a complete description of the moduli space of minimal surfaces of...

We introduce a new equivalence relation for complete algebraic varieties with canonical singularities, generated by birational equivalence, by flat algebraic deformations (of varieties with canonical singularities), and by quasi-´ etale morphisms, i.e., morphisms which are unramified in codimen-sion 1. We denote the above equivalence by A.Q.E.D. : = Algebraic-Quasi-´ Etale-Deformation. A comple...
