From exact results to gauge dynamics on ℝ3 × S 1

We revisit the vacuum structure of the N = 1 Intriligator-Seiberg-Shenker model on ℝ3× S1. Guided by the Cardy-like asymptotics of its Romelsberger index, and building on earlier semi-classical results by Poppitz and Ünsal, we argue that previously overlooked non-perturbative effects generate a Higgs-type potential on the classical Coulomb branch of the low-energy effective 3d N = 2 theory. In particular, on part of the Coulomb branch we encounter the first instance of a dynamically-generated...

On matrix models and their q-deformations

Motivated by the BPS/CFT correspondence, we explore the similarities be- tween the classical β-deformed Hermitean matrix model and the q-deformed matrix models associated to 3d N = 2 supersymmetric gauge theories on D2×qS1 and Sb3 by matching parameters of the theories. The novel results that we obtain are the correlators for the models, together with an additional result in the classical case consisting of the W -algebra representation of the generating function. Furthermore, we also obtain ...

Towards a model on junk bond contagion

Understanding contagion mechanisms is important to identify key factors that may have predictive information value or confirmatory information value for market trading. After reviewing the current literature on financial contagion, this article focuses on specific characteristics of junk bonds that are particularly sensitive to contagion situations. Next, it proposes a new framework to disentangle factors that may act as predictive and proactive and those that may represent confirming informa...
