Exceptional Groups and del Pezzo Surfaces
Let Er, r = 6, 7, 8 denote the simply connected form of the complex linear group whose root system is of type Er. We extend this series to 3 ≤ r ≤ 8 by setting E5 = D5, E4 = D4, and E3 = A1 × A2, again with the understanding that Er denotes the simply connected form of the corresponding complex linear group of type Er. It has long been known that there are deep connections between Er and del Pe...
متن کاملExceptional Collections and del Pezzo Gauge Theories
Stacks of D3-branes placed at the tip of a cone over a del Pezzo surface provide a way of geometrically engineering a small but rich class of gauge/gravity dualities. We develop tools for understanding the resulting quiver gauge theories using exceptional collections. We prove two important results for a general quiver gauge theory: 1) we show the ordering of the nodes can be determined up to c...
متن کاملThree-block exceptional collections over Del Pezzo surfaces
We study complete exceptional collections of coherent sheaves over Del Pezzo surfaces, which consist of three blocks such that inside each block all Ext groups between the sheaves are zero. We show that the ranks of all sheaves in such a block are the same and the three ranks corresponding to a complete 3-block exceptional collection satisfy a Markov-type Diophantine equation that is quadratic ...
متن کاملSingular Del Pezzo Surfaces Whose Universal Torsors Are Hypersurfaces
We classify all singular Del Pezzo surfaces of degree three or greater whose universal torsor is an open subset of a hypersurface in affine space. Equivalently, their Cox ring is a polynomial ring with exactly one relation. For all 20 types with this property, we describe the Cox ring in detail.
متن کاملNonnormal Del Pezzo Surfaces
0.1 Throughout this paper, a del Pezzo surface is by definition a connected, 2-dimensional, projective k-scheme X,OX(1) that is Gorenstein and anticanonically polarised; in other words, X is Cohen–Macaulay, and the dualising sheaf is invertible and antiample: ωX ∼= OX(−1). For example, X = X3 ⊂ P 3 an arbitrary hypersurface of degree 3. Under extra conditions, del Pezzo surfaces are interesting...
