In this paper, a tumor-immune interaction model has been analyzed via
Caputo-Fabrizio fractional derivative operator with exponential kernel.
Existence of solution of the model has been established with a fixed-point
method and then it demonstrated the uniqueness of solution also. The
stability of the model has been analyzed with the help of Hyers-Ulam
stability approach and then numerical solution by using the Adam-Basford
method. The results are further examined in detail with simulations for
different fractional derivative values.
