Stability analysis and numerical simulation of nonlocal extended epidemic models using positivity-preserving scheme

Abstract In this paper we introduce a robust numerical framework for simulating the nonlocal extended epidemic models that incorporate the fractional diffusion to capture the complex spatial–temporal dynamics of disease spread. The presented numerical scheme uses the Fourier spectral approach for sp...
