The twisted index and topological saddles

چکیده
A bstract The twisted index of 3d $$ \mathcal{N} N = 2 gauge theories on S 1 × Σ has an algebro-geometric interpretation as the Witten effective supersymmetric quantum mechanics. In this paper, we consider contributions to mechanics from topological saddle points in localisation abelian theories. Topological saddles are configurations where matter fields vanish and symmetry is unbroken, which exist for non-vanishing Chern-Simons levels. We compute both vortex-like show that their combination recovers Jeffrey-Kirwan residue prescription its wall-crossing.

On 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 کاملTwisted 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 کاملRelationships between Randic index and other topological indices
Let $G$ be a graph with vertex set $V(G)$ and edge set $E(G)$, and let $d_u$ denote the degree of vertex $u$ in $G$. The Randi'c index of $G$ is defined as${R}(G) =sum_{uvin E(G)} 1/sqrt{d_ud_v}.$In this paper, we investigate the relationships between Randi'cindex and several topological indices.
متن کاملThe topological B model as a twisted spinning particle
The B–twisted topological sigma model coupled to topological gravity is supposed to be described by an ordinary field theory: a type of holomorphic Chern–Simons theory for the open string, and the Kodaira–Spencer theory for the closed string. We show that the B model can be represented as a particle theory, obtained by reducing the sigma model to one dimension, and replacing the coupling to top...
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.
