Conservative Solutions of One-Dimensional Nonlinear Distribution Processes with Drift
TL;DR: In this paper, a one-dimensional quasilinear autonomous parabolic equation is considered, which generalizes a well-known equation which occurs, for example, in the theory of radiation heat conduction and diffusion in porous media.
Journal ArticleDOI
Nonlinear diffusion and particle production in relativistic systems
TL;DR: In this article, the short parton production phase in high-energy heavy-ion collisions is treated analytically as a nonlinear diffusion process, and the initial buildup of the rapidity density distributions of produced charged hadrons within τ p ≃ 0.25 fm/c occurs in three sources during the colored partonic phase.

A numerical method for an inhomogeneous nonlinear diffusion problem
TL;DR: In this article, a numerical method for the solution of an inhomogeneous nonlinear diffusion problem that arises in a variety of applications is presented, where the diffusion coefficient in the underlying diffusion process is concentration- as well as distance- dependent.
