Dynamic analysis of a Caputo fractional-order SEIR model with a general incidence rate

Abstract This study develops a fractional-order SEIR model with asymptomatic infections and memory effects, introducing a generalized incidence rate to better reflect the nonlinear characteristics of transmission. The Caputo fractional derivative is used to capture memory effects and non-locality, d...
