Variational and Semigroup Methods for Waves and Diffusion in Networks    [PDF]

Marjeta Kramar Fijavz, Delio Mugnolo, and Eszter Sikolya

We study diffusion and wave equations in networks. Combining semigroup and variational methods we obtain well-posedness and many nice properties of the solutions in general L^p -context. Following earlier articles of other authors, we discuss how the spectrum of the generator can be connected to the structure of the network. We conclude by describing asymptotic behavior of solutions to the diffusion problem.
