Statistical estimation of a nonlinear diffusion system in a gravitational field

A nonlinear diffusion equation with a diffusion coefficient depending on the number density of diffusing particles affected by gravity is solved approximately for a stationary state. As a result, expectation values of both the number density and its position are estimated to explain the shifts from...
