The paper “On differentiability of volume time functions” co-authored by Piotr Chrusciel (Vienna), James Grant, and Ettore Minguzzi (Firenze) has been accepted for publication by the Annales Henri Poincare.  The online version at Springer is here and the arXiv version is here.  The paper shows differentiability of a class of Geroch’s volume functions on globally […]

The third meeting in the MiLS (Mathematics in Life Sciences) series was held in the Department of Mathematics at Surrey on Wednesday 28 September.  The theme of this conference is Mathematics of Biological Rhythms.  A programme with talk titles and abstracts is here.  Gianne Derks leads the local organisation, Anne Skeldon is the first speaker, […]

The paper “Continuation and bifurcation of grain boundaries in the Swift-Hohenberg equation“, co-authored by David Lloyd and Arnd Scheel (University of Minnesota) has been accepted for publication in the SIAM Journal of Applied Dynamical Systems.  The final form manuscript can be found on the arXiv here.

Congratulations to Antonio Pitelli who passed his PhD viva today (Friday 23 September) with minor corrections.  The title of his thesis is “Dualities and Integrability in Low Dimensional AdS/CFT“. The examiners were Bogdan Stefanski (City University, London) and Jan Gutowski.  Antonio was jointly supervised by Alessandro Torrielli and Martin Wolf.

The paper “Stagnation-point flows with stretching surfaces: A unified formulation and new results“, co-authored by Matt Turner and Patrick Weidman (University of Colorado, Boulder) has been accepted for publication in European Journal of Mechanics/B Fluids. The paper investigates the stability of stagnation point flows coupled to stretching surfaces below the flow. The theory presents a […]

The paper AdS3/CFT2 and q-Poincare’ superalgebras co-authored by Joakim Strömwall and Alessandro Torrielli, has been accepted for publication in the Journal of Physics A. In the paper they discover that a certain deformation of the 1+1 dimensional Poincare’ superalgebra is exactly realised in the massless sector of the AdS3/CFT2 integrable scattering problem. They obtain a […]
