Twisted sheaves and the period-index problem
We use twisted sheaves and their moduli spaces to study the Brauer group of a scheme. In particular, we (1) show how twisted methods can be efficiently used to re-prove the basic facts about the Brauer group and cohomological Brauer group (including Gabber’s theorem that they coincide for a separated union of two affine schemes), (2) give a new proof of de Jong’s periodindex theorem for surface...
متن کاملOn the forgotten topological index
The forgotten topological index is defined as sum of third power of degrees. In this paper, we compute some properties of forgotten index and then we determine it for some classes of product graphs.
متن کاملConstructing Simplicial Complexes over Topological Spaces
The first step in topological data analysis is often the construction of a simplicial complex. This complex approximates the lost topology of a sampled point set. Current techniques often assume that the input is embedded in a metric – often Euclidean – space, and make significant use of the underlying geometry for efficient computation. Consequently, these techniques do not extend to non-Eucli...
متن کاملThe Period-index Problem in Wc-groups Iii: Biconic Curves
This note continues our study of the period-index problem in the Weil-Châtelet group of an elliptic curve, begun in [6]. In this paper, we conjectured that for any elliptic curve E/K defined over a number field and any prime number p, there exists an infinite subgroup G of H(K,E), every nonzero element of which has period p and index p. This conjecture was proved when E has full p-torsion defin...
متن کاملModuli of Twisted Orbifold Sheaves and the Period-index Problem
We prove that certain stacks of slope-semistable twisted sheaves on orbisurfaces are non-empty and geometrically irreducible. Using these results, we prove the standard period-index conjecture for Brauer classes over function fields of surfaces over finite fields.
