This paper aims to contribute to research on the question of the stabilization or destabilization of a deterministic dynamical system (differential equation, partial differential equation, or functional differential equation) by a noise perturbation, and in particular, perturbations which transform the differential equation (or FDE) to one of Itô-type. Mao has written an interesting paper [9] d...

Abstract SEIR compartmental model for COVID-19 pandemic (SEIR_COVID) with exposed group is proposed and analysed in this paper. The steady state of determined to control the pandemic. Zero Disease equilibrium are presented SEIR_COVID model. In each case, prints locally asymptotically stable under certain conditions. Routh-Hurwitz criteria used study stability COVID-19. This showed that using wi...
