Gert van der Heijden appointed to a Royal Society Research Fellowship

Gert van der Heijden, currently a postdoctoral research fellow working with Michael Thompson in the Centre for Nonlinear Dynamics at UCL, has been awarded a Royal Society Research Fellowship for 5 years to continue his research in the application of nonlinear dynamics techniques to localisation phenomena in the post-buckling behaviour of engineering structures. Mathematically, this work involves the theoretical and numerical analysis of homoclinic and heteroclinic bifurcations. He will remain at UCL and start his fellowship on 1 October 1999.

Visit of Dr S. Derkachov to Leeds (September-October 1999)

Dr S. Derkachov, a Reader at the Department of Mathematics, St. Petersburg Institute of Technology, Russia, works on quantum field theory, quantum chromodynamics and integrable systems. He will visit the University of Leeds for 1 month in September-October 1999. His visit is supported by the Royal Society under a scheme for short visits. It is anticipated that he will give seminars in Leeds and York on Baxter's Q-operator for homogeneous XXX spin chain and will pursue research on quantum Backlund transformations.

Visit of Professor V.I. Inozemtsev to Leeds (October-November 1999)

Professor V.I. Inozemtsev, a research fellow at the Laboratory of Theoretical Physics of the Joint Institute of Nuclear Research in Dubna, Russia, works on integrable models of statistical mechanics and theory of multidimensional Riemann theta functions. He will visit the University of Leeds for 1 month in October-November 1999 under the International Short Visits scheme 5 of the London Mathematical Society. He will give an Algebra Seminar in Leeds on October 11th entitled: Invariants of linear combinations of transpositions. It is anticipated that he will also visit the University of York on October 20 and Edinburgh University on October 25-27 where he will give seminars on Bethe Ansatz equations for quantum spin chains with elliptic exchange.
