26 p, 1.5 MB Fronts propagating with signal dependent speed in limited diffusion and related Hamilton-Jacobi formulations / Serna, Susana (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Marquina, Antonio (Universitat de València. Departament de Matemàtiques)
We consider a class of limited diffusion equations and explore the formation of diffusion fronts as the result of a combination of diffusive and hyperbolic transport. We analyze a new class of Hamilton-Jacobi equations arising from the convective part of general Fokker-Planck equations ruled by a non-negative diffusion coefficient that depends on the unknown and on the gradient of the unknown.

63 p, 650.6 KB Flux limited generalized porous media diffusion equations / Caselles, Vicent
We study a class of generalized porous media type flux limited diffusion equations and we prove the existence and uniqueness of entropy solutions. We compute the Rankine-Hugoniot condition on the jump set for solutions which are of locally bounded variation in space and time. [...]
