Hypergraph spectral

WebWe discuss different types of contagion models in this hypergraph setting and derive spectral conditions that characterize whether the disease vanishes. We study both the exact individual-level stochastic model and a deterministic mean field ODE approximation. Numerical simulations are provided to illustrate the analysis. WebThe spectral radius of hypergraph His de ned as spectral radius of its adjacency tensor, denoted by ˆ(H). In [3] the weak irreducibility of nonnegative tensors was de ned. It was proved that an r-uniform hypergraph His connected if and only if its adjacency tensor A(H) is weakly irreducible (see [3] and [14]).
