GAPS IN DYNAMICAL DEGREES FOR ENDOMORPHISMS AND RATIONAL MAPS
Résumé
We study the ratio of dynamical degrees λ_1(f) 2 /λ_2(f) for regular, dominant endomorphisms of smooth complex projective surfaces, and obtain a gap property: for λ_2 (f) ≤ D, there is a uniform ε(D) > 0 such that this ratio is never contained in ]1, 1 + ε(D)[. The proof is a simple variation on the main theorems of [6].
