WebIn all cases, these surfaces satisfy weak approximation (assuming they have a point). July 24th: Showed that del Pezzo surfaces of degree 5 always have a rational point and are birational to the plane, over the ground field. Introduced the Azumaya Brauer group and the cohomological Brauer group (which coincide for nice varieties). WebApr 21, 2016 · For each del Pezzo surface with du Val singularities, we determine whether it admits a -polar cylinder or not. If it allows one, then we present an effective -divisor that is -linearly equivalent to and such that the open set is a cylinder. WebSep 6, 2024 · Del Pezzo surfaces are one of the most investigated subjects in the classical algebraic geometry. A smooth surface S is called a del Pezzo surface if its anti-canonical divisor -K_S is ample, and it is of degree d if the self-intersection number (-K_S)^2 is d. The degree d is an integer from 1 to 9, as is well known. phim amagi brilliant hd
