Explaining conflict violence in terms of conflict actor dynamics

Katerina Tkacova, Annette Idler, Neil Johnson +1

We study the severity of conflict-related violence in Colombia at an unprecedented granular scale in space and across time. Splitting the data into different geographical regions a…

Dessins d'Enfants, Seiberg-Witten Curves and Conformal Blocks

Jiakang Bao, Omar Foda, Yang-Hui He +4

We show how to map Grothendieck's dessins d'enfants to algebraic curves as Seiberg-Witten curves, then use the mirror map and the AGT map to obtain the corresponding 4d $\mathcal{N…

More on products of Baire spaces

Rui Li, László Zsilinszky

New results on the Baire product problem are presented. It is shown that an arbitrary product of almost locally ccc Baire spaces is Baire; moreover, the product of a Baire space an…

The Motion Of A Spring Released From Uniform Circular Motion

Thomas Dooling, Jeffrey Regester, Matthew Carnaghi +1

A weak spring is connected at one end to a rotor turning at constant angular velocity. The spring extends to a stretched length as determined by the spring mass, rest length, sprin…

Essential Circles and Gromov-Hausdorff Convergence of Covers

Conrad Plaut, Jay Wilkins

We give various applications of essential circles (introduced in an earlier paper by the authors) in a compact geodesic space X. Essential circles completely determine the homotopy…

The entropy of co-compact open covers

Zheng Wei, Yangeng Wang, Guo Wei

Co-compact entropy is introduced as an invariant of topological conjugation for perfect mappings defined on any Hausdorff space(compactness and metrizability not necessarily requir…

Gauge theory in deformed N=(1,1) superspace

I. L. Buchbinder, E. A. Ivanov, O. Lechtenfeld +2

We review the non-anticommutative Q-deformations of N=(1,1) supersymmetric theories in four-dimensional Euclidean harmonic superspace. These deformations preserve chirality and har…

Preservation of log-concavity on summation

Oliver Johnson, Christina Goldschmidt

We extend Hoggar's theorem that the sum of two independent discrete-valued log-concave random variables is itself log-concave. We introduce conditions under which the result still…
