Ω-Background and the Nekrasov Partition Function
In this talk we’ll aim to make sense of the Nekrasov partition function (as introduced in Nekrasov’s ICM address [Nek03]) as the partition function in a twisted deformed N = 2 gauge theory. While making the deformation is unnecessary – without it we’re just talking about the partition function in Donaldson-Witten theory – deforming the theory eliminates IR divergences, allowing a direct mathema...
متن کاملThe Nekrasov Conjecture for Toric Surfaces
The Nekrasov conjecture predicts a relation between the partition function for N = 2 supersymmetric Yang–Mills theory and the Seiberg-Witten prepotential. For instantons on R, the conjecture was proved, independently and using different methods, by Nekrasov-Okounkov, Nakajima-Yoshioka, and Braverman-Etingof. We prove a generalized version of the conjecture for instantons on noncompact toric sur...
متن کاملThe Partial Entropy Decomposition: Decomposing multivariate entropy and mutual information via pointwise common surprisal
Obtaining meaningful quantitative descriptions of the statistical dependence within multivariate systems is a difficult open problem. Recently, the Partial Information Decomposition (PID) was proposed to decompose mutual information (MI) about a target variable into components which are redundant, unique and synergistic within different subsets of predictor variables. Here, we propose to apply ...
متن کاملDecomposing Current Mortality Differences Into Initial Differences and Differences in Trends: The Contour Decomposition Method
This study proposes a new decomposition method that permits a difference in an aggregate measure at a final time point to be split into additive components corresponding to the initial differences in the event rates of the measure and differences in trends in these underlying event rates. For instance, when studying divergence in life expectancy, this method allows researchers to more easily co...
متن کاملDecomposing Deunionization: A sequential decomposition of the drop in collective bargaining coverage
Union representation is in strong decline in most industrialized countries. What drives this decline? We contribute to answering this question by developing and implementing a detailed decomposition approach based on Fairlie (2005). Using linked employer-employee data from the German Structure of Earnings Survey for 2001 and 2006, we document a sharp drop in collective bargaining coverage that ...
