Abstract: In this talk, after recalling results about the spectrum of the normalized Laplacian of a graph, I shall introduce a Laplace operator for a class of hypergraphs that model chemical reaction systems, and I shall present the corresponding spectral theory. This will include Cheeger type inequalities. The talk will represent joint work with Raffaella Mulas and Zhang Dong.
