Description
In the first part of the talk I'll take the risk of doing history of mathematics, presenting results of Cayley, Cremona and Halphen on deformations of elliptic fibrations (without sections). After, I'll show some experiments of degenerations of the configurations treated by these authors. At last, I'll give some ideas of Brunella's general result on deformations of elliptic fibrations and singular holomorphic foliations, which is not widely diffused.
