Abstract:Alongside with conic bundles, del Pezzo surfaces are possible outcomes of the Minimal Model Program ran on a geometrically rational surface. Thus, many questions about birational geometry and birational automorphisms of geometrically rational surfaces reduce to similar questions for del Pezzo surfaces. I will survey some known results concerning birational models and birational automo...
