Abstract:
We study the qualitative behavior of solutions to the Vlasov equation
with strong external magnetic field and oscillating electric
field. This model is relevant to the understanding of isotop
resonant separation. We show that the effective equation is
a kinetic equation with a memory term. This memory term involves
a pseudo-differential operator whose kernel is characterized by an
integral equation involving Bessel functions. The kernel is explicitly
given in some particular cases.
