Resumen de On Cremona transformations of P3 which factorize in a minimal form

Ivan Pan

• We consider Cremona transformations of the complex projective space of dimension 3 which factorize as a product of two elementary links of type II, without small contractions, connecting two Fano 3-folds. We show there are essentially eight classes of such transformations and give a geometric description of elements in each of these classes.
