ABSTRACT
Despite official anti-corruption measures, Nigeria’s chronic corruption is the country’s greatest threat to stability, raising concerns about the country’s institutions’ ability to combat corruption. A model for the spread of corruption is developed and analyzed. The model’s basic reproduction number, equilibriums, and stabilities are all taken into account. The Caputo fractional derivative operator of order is used to generate the model scheme of non-integer differential equations. The Laplace-Adomian Decomposition Method is used to estimate a solution to a set of non-integer differential equations. Numerical simulations are presented to demonstrate the method’s dependability and simplicity.
