摘要:
We study the pointwise (in both space and time variables) behavior of the FokkerPlanck equation with flat potentials.
A precise description of the solution is given, including the initial singularity, large time behavior and spatially asymptotic
behavior. The initial layer is dominated by KolmogorovFokkerPlanck solution, the large time behavior is dominated by
diffusion fluid wave, and the solution decays exponentially or subexponentially at spacelike region. Moreover, the structure
of the solution highly depends on the potential function. How to apply the similar idea to linearized Landau equation will
be mentioned. If time permits, we will also discuss the similarities and differences between these equations and the cutoff
Boltzmann equation.
