Vertical mergers without foreclosure
Abstract The typical concern about vertical mergers is the foreclosure of downstream rivals. In a vertically related industry where downstream firms have a common supplier, margins can reveal whether upstream competition constrains that supplier.

Spatial and spatiotemporal volatility models: A review
Abstract Spatial and spatiotemporal volatility models are a class of models designed to capture spatial dependence in the volatility of spatial and spatiotemporal data. Spatial dependence in the volatility may arise due to spatial spillovers among locations; that is, in the case of positive spatial dependence, if two locations are in close proximity ...

ABSTRACT This study aims to identify differences in the functional neural connectivity of the brain of paediatric patients with obstructive sleep apnea. Using EEG signals from 3673 paediatric patients, we grouped subjects into OSA or control groups based on sleep oxygen desaturation levels and apnea‐hypopnea index (AHI), and applied topological data ...

Non-additive Lie centralizer of strictly upper triangular matrices
Let F be a field of zero characteristic, let Nn (F ) denote the algebra of n × n strictly upper triangular matrices with entries in F , and let f : Nn (F ) → Nn (F ) be a non-additive Lie centralizer of Nn (F ) , that is, a map satisfying that f ([X, Y ])
