Analysis of the dynamics of hepatitis E virus using the Atangana-Baleanu fractional derivative

The pivotal aim of the present work is to analyse the dynamics of fractional mathematical model of the hepatitis E virus using the fractional Atangana-Baleanu (AB) derivative. The existence and uniqueness of the solution obtained for the proposed model are presented with the help of the fixed-point hypothesis. The Adams-Bashforth technique is employed to analyse and find the solution for the future model, and the numerical simulations have been conducted in order to validate the efficiency of the Atangana-Baleanu derivative. The present investigation shows that the dynamics of the hepatitis E virus model noticeably depends on the time instant as well as the time history, which can be efficiently modelled by employing the theory of fractional calculus.
