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.

19 p, 692.2 KB A bundle-Newton method for nonsmooth unconstrained minimization / Luksan, Ladislav ; Vlcek, Jan
An algorithm based on a combination of the polyhedral and quadratic approximation is given for finding stationary points for unconstrained minimization problems with locally Lipschitz problem functions that are not necessarily convex or differentiable. [...]
