The concept of molecular structure is one the most important concepts in the development of the scientific knowledge of the XX century. As a matter of fact the reasoning based on the molecular structure has been the main engine for the great development of physical chemistry, molecular physics, organic chemistry, quantum chemistry, chemical synthesis, polymer chemistry, medicinal chemistry, etc...

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...
