Abstract

‎In recent times‎, ‎there has been an increasing focus on investigating the therapeutic capacity of virus particles in the management of cancer‎. ‎This paper introduces a novel discrete-time mathematical model with fractional-order of oncolytic virotherapy‎. ‎The model captures the complex behavior of how cancer cells and virus particles interact‎, ‎aiming to elucidate the process of infecting and eliminating cancer cells in the absence of immune involvement‎. ‎To evaluate the efficacy of cancer-targeting virus treatment‎, ‎we perform an in-depth analysis of both the local stability and the bifurcation trends observed in our framework‎. ‎By selecting appropriate bifurcation parameters‎, ‎we verify the occurrence of codimension one bifurcations‎, ‎for instance‎, ‎fold‎, ‎flip as well as Neimark-Sacker (N-S)‎, ‎as well as codimension-two flip-N-S bifurcations‎. ‎ The identification of these bifurcation types is established by deriving necessary and sufficient conditions using algebraic criterion methods‎. ‎In these criteria‎, ‎the reliance does not lie in the attributes of the eigenvalue coefficients from the characteristic equation of the Jacobian matrix but rather on the coefficients of the Jacobian matrix's characteristic equation itself‎. ‎Consequently‎, ‎we have semi-algebraic systems comprising equations‎, ‎inequalities‎, ‎and inequalities‎. ‎This algebraic methodology provides appropriate conditions for both codimension one as well as codimension-two bifurcations in high-dimensional maps‎. ‎Finally‎, ‎numerical simulations were conducted to validate our theoretical findings‎. ‎Our study concludes that the correlated increase between cancer cell proliferation and the therapeutic virus indeed resulted in the anticipated infection within the cancer cells‎. ‎While complete eradication of cancer cells using viral therapy alone is not impossible‎, ‎it requires specific conditions‎.
