Chaos, Solitons & Fractals
In this paper, we formulate a new model of a particular type of influenza virus called AH1N1/09 in the
framework of the four classes consisting of susceptible, exposed, infectious and recovered people. For the firsttime, we here investigate this model with the help of the advanced operators entitled the fractal–fractional operators with two fractal and fractional orders via the power law type kernels. The existence of solution for the mentioned fractal–fractional model of AH1N1/09 is studied by some special mappings such as 𝜙 − 𝜓- contractions and 𝜙-admissibles. The Leray–Schauder theorem is also applied for this aim. After investigatingthe stability criteria in four versions, to approximate the desired
numerical solutions, we implement Adams–Bashforth (AB) scheme and simulate the graphs for different data on the fractal and fractional orders. Lastly, we convert our fractal–fractional AH1N1/09 model into a fractional model via the generalized Liouville–Caputotype (GLC-type) operators and then, we simulate new graphs caused by the new numerical scheme called Kumar–Erturk method.
