Abstract:We compute global log canonical thresholds of a large class of quasismooth well-formed del Pezzo weighted hypersurfaces in ?(a 0,a 1,a 2,a 3). As a corollary we obtain the existence of orbifold Kähler-Einstein metrics on many of them, and classify exceptional and weakly exceptional quasismooth well-formed del Pezzo weighted hypersurfaces in ?(a 0,a 1,a 2,a 3).
