The paper “The future is not always open“, co-authored by James Grant, Michael Kunzinger (Vienna), Clemens Sämann (Vienna), and Roland Steinbauer (Vienna), has been published in Letters in Mathematical Physics. The paper demonstrates the breakdown of several fundamentals of Lorentzian causality theory in low regularity. A link to the published version is here. The diagram […]

Congratulations to Imran Usmani for passing his PhD confirmation examination. It was held on Wednesday 22 January, and the examiners were Vikki Revell (Surrey Sleep Research Centre) and Gianne Derks. The title of Imran’s project is “A mathematical modelling approach to the prediction of circadian phase“. The project supervisors are Anne Skeldon and Derk-Jan Dijk […]

Martin Wolf is visiting the Mathematics Department at Heriot-Watt University this week and giving a talk in the Edinburgh Mathematics Physics Seminar on Wednesday 22 January. The title is “Homotopy algebras and scattering amplitudes“. Abstract (click on title) and further information can be found here.

The paper “On the Lieb-Thirring constant on the torus“, co-authored by Sergey Zelik, Alexei Illyin (Keldysh, Moscow), and Ari Laptev (Imperial College London), has been published in the Russian journal Математические заметки. The case of the two-torus is treated in the paper. A link to the Russian version is here, and a link to the […]

The paper “A method for generating coherent spatially explicit maps of seasonal paleoclimates from site-based reconstructions“, co-authored by Sean Cleator, Sandy Harrison (Reading University), Nancy Nichols (Reading University), Iain Prentice (Imperial College London), and Ian Roulstone, has been published in the Journal of Advances in Modeling Earth Systems. The paper employs a 3-D-variational technique, site-based […]

The paper “Norms and scalar products for AdS_3“, co-authored by Juan Miguel Nieto and Alessandro Torrielli, has been accepted for publication in the Journal of Physics A. The paper computes scalar products and norms of Bethe vectors in the massless sector of AdS_3 integrable superstring theories. A link to abstract and final form arXiv version […]
