That’s the startling finding of a new game theory paper by researchers at HEC Montréal published in the January issue of Mathematical Social Sciences.…

Differential equations and the role of coincidence

In a project funded by the Austrian Science Fund FWF, a team directed by mathematician Erika Hausenblas is investigating how the pressure of flowing liquids can be described when taking into account random perturbations. Differential equations are a physicist’s most important tool. From Newton’s law of gravitation to quantum physics one will scarcely find a…

Mathematical theorem finds gerrymandering in PA congressional district maps

The current congressional districting of the state of Pennsylvania. Credit: Carnegie Mellon University Pennsylvania’s congressional district maps are almost certainly the result of gerrymandering according to an analysis based on a new mathematical theorem on bias in Markov Chains developed by Carnegie Mellon University and University of Pittsburgh mathematicians. Their findings are published in the…
