2006-12-11Cristel ChandreNoncanonical Hamiltonian formulation: toward gyrokinetics

I will review an article on a noncanonical Hamiltonian treatment of the
motion of a charged particle in electromagnetic fields, following R.G.
Littlejohn [J. Math. Phys. 20, 2445 (1979)]. Averaging techniques lead
to the equations of the so-called guiding center and to the gyrokinetics
equations used in plasma physics.

2006-10-04Predrag CvitanovicTheory of compact groups, discrete and continuous, continued.

An introduction to representation theory of compact Lie groups and finite
discrete groups, with the goal of applying this to fluid flows with
continuous symmetries - pipe and plane Couette. We'll sing it until we get
it right.
