The paper “Lieb–Thirring constant on the sphere and on the torus” co-authored by A. Ilyin, A. Laptev, and S. Zelik, has been published in the Journal of Functional Analysis. The paper proves, on the 2-sphere and on the 2-torus, the Lieb–Thirring inequalities with improved constants, for orthonormal families of scalar and vector functions. A link […]

The paper “Eigenvalue estimates for multi-form modified Dirac operators“, co-authored by Jan Gutowski and George Papadopoulos (King’s College London), has been published in the Journal of Geometry and Physics. The paper gives estimates for the eigenvalues of multi-form modified Dirac operators which are constructed from a standard Dirac operator with the addition of a Clifford […]

The paper “Energy minimising N-covering maps in two dimensions“, co-authored by Jon Bevan and Jonathan Deane, has been accepted for publication in the Springer journal Calculus of Variations and Partial Differential Equations (link here).

The paper “A proof of validity for multiphase Whitham modulation theory“, co-authored by Tom Bridges, Anna Kostianko, and Guido Schneider (Universität Stuttgart), has been published by the Proceedings A of the Royal Society of London. A link to the final form arXiv version of the paper is here, and a link to the published version […]

Congratulations to Michael Foskett for passing his PhD viva on Wednesday 16 September! Michael’s thesis is entitled “Geometry of quantum hydrodynamics in theoretical chemistry“. The External Examiner was Klas Modin (Chalmers University, Sweden) and the Internal was Tom Bridges. The viva was chaired by Alessandro Torrielli. The project was supervised by Cesare Tronci, and his […]

Sergey Zelik is giving the opening talk at the International Video-workshop on Infinite Dimensional Dynamical Systems (link here), to be held 12-19 September at Dongua University in Shanghai, China. The conference will be broadcast on VooV (Chinese analogue of Zoom). Sergey‘s talk is on “Deterministic and random attractors for a wave equation with sign changing […]
