We consider a model for the flow of granular matter which was proposed byHadeler and Kuttler (Granular Matter, 1999). The original model uses the height ofthe standing layer and the thickness of the moving layer as the unknowns.By introducing the slope the standing layer, one arrives at a 2 by 2 system ofbalance laws. This system is weakly linea...

The current talk is concerned with the spectral theory, in particular, the principal eigenvalue theory, of nonlocal dispersal operators with time periodic dependence, and its applications. Nonlocal andrandom dispersal operators are widely used to model diffusion systems in applied sciences and share many properties.There are also some essential ...

The current talk is concerned with transition fronts of nonlocal dispersal evolution equations in heterogeneous media. As it is known, solutions of nonlocal dispersal evolution equations do not become smoother in space as time elapses. This lack of space regularity would cause a lot of difficulties in studying transition fronts in nonlocal dispe...

The current talk is concerned with traveling wave solutions of reaction diffusion equations in random media.I will first introduce the concept of random traveling wave solutions and present a general theorem about theexistence of such traveling wave solutions. I will then discuss the existence, uniqueness, and stability of random traveling wave ...
