Speaker: Prof. Boris Dubrovin (SISSA) http://people.sissa.it/~dubrovin/ Time: Friday, August 3, 2:30--3:30PM Room: Chemistry Lecture Theatre 4 (Sydney University) Joint Colloquium web site: http://www.maths.usyd.edu.au/u/SemConf/JointColloquium/index.html ----------------------------------------------- Title: On Geometrical Structures and Properties of Solutions to Hamiltonian Partial Differential Equations Abstract: in the talk we will study Hamiltonian perturbations of hyperbolic systems of partial differential equations (PDEs) with one spatial variable. The deformation theory of integrable PDEs will be discussed. We also consider the behaviour of solutions to such systems at the point of "phase transition" from regular to oscillatory regime. ----------------------------------------------- Lunch with speaker: we meet around 1PM at the Level 2 entry to Carslaw Building.
