Plane Cremona transformations of fixed degree

Fixed a positive integer d, plane Cremona transformations of degree d form a quasi-projective variety. Its decomposition in irreducible components, their dimension and the properties of the general element of each irreducible component will be presented. Its connectedness will be discussed for small values of d. This is joint work with Cinzia Bisi and Massimiliano Mella.
