摘要：
In this article, a nonlinear SIS model with nonlocal disease transmission rate and diffusion in space is studied. Nonlinearity in the model is due to the dependence of the disease transmission rate on the total population. Semigroup theory is used to establish existence and uniqueness of solution of this nonlinear parabolic initial boundary value problem. Stability of the steady state is investigated using spectral analysis of the perturbed operator. © The Author(s) under exclusive licence to Sociedade Brasileira de Matemática Aplicada e Computacional 2025.
