A general strategy is given for the classification of graphs of rational surface singularities. For each maximal rational double point configuration we investigate the possible multiplicities in the f...

The aim of this paper is to construct many examples of rational surface automorphisms
with positive entropy by means of the concept of orbit data. We show that if an orbit
data satisfies some mild c...
