C. Favre - Dynamical degree 1
Dynamical degrees were introduced by Russakovskii and Shiffman in 1997. They measure the growth of preimages of subvarieties of a fixed dominant rational map of a projective variety\, and control many dynamical features of this map. In this first set of lectures\, we shall define dynamical degrees using positivity properties of divisor classes\, and explain how to compute them in low dimension and in some significant examples.
