The Economic Consequences of Social Unrest: Evidence from Initial Public Offerings
European Financial Management, EarlyView.ABSTRACT Prior research attributes negative stock market performance following episodes of social unrest to elevated uncertainty. However, social unrest does not solely increase uncertainty but separately acts to decrease investor sentiment. To determine which effect dominates, we study initial public offering (IPO) underpricing, which responds ...

Topology of 3-dimensional manifolds [PDF]
ریاضی و جامعهThis is the second paper from a trio which reviews some of the progress in low dimensional topology in the past century. Starting with the work of Poincare in the last years of 19th century and first few years of 20th century, we review the major steps ...

Combinatorial Ricci Flows on Surfaces
Journal of Differential Geometry, 2003 We show that the analog of Hamilton's Ricci flow in the combinatorial setting produces solutions which converge exponentially fast to Thurston's circle packing on surfaces. As a consequence, a new proof of Thurston's existence of circle packing theorem is obtained. As another consequence, Ricci flow suggests a new algorithm to find circle packings.

Equine Veterinary Journal, EarlyView.Abstract Background Obesity has been associated with human obstructive sleep apnoea and canine brachycephalic obstructive airway syndrome. The effect of body condition score (BCS) on structures of the oropharynx, nasopharynx and upper airway of the horse has not been investigated. Objectives To investigate the effect of BCS on tongue measurements, soft

Ricci Solitons in β-Kenmotsu Manifolds
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 The object of the present paper is to study Ricci soliton in β-Kenmotsu manifolds. Here it is proved that a symmetric parallel second order covariant tensor in a β-Kenmotsu manifold is a constant multiple of the metric tensor.

Forman-Ricci Flow for Change Detection in Large Dynamic Data Sets
Axioms, 2016 We present a viable geometric solution for the detection of dynamic effects in complex networks. Building on Forman’s discretization of the classical notion of Ricci curvature, we introduce a novel geometric method to characterize different types of real-
