通过速度图变换,给出了SIR模型的保结构离散化,并给出了其离散SIR模型的可积性条件。对于那些可积的离散SIR模型,我们得到了它们的精确解和守恒量。如果我们为我们提出的离散SIR模型中的一个选择适当的参数,它将守恒SIR模型的守恒量。我们还研究了一个超离散的离散SIR模型。
Structure-preserving discretizations of the SIR model are presented by focusing on the hodograph transformation and the conditions for integrability for their discrete SIR models are given. For those integrable discrete SIR models, we derive their exact solutions as well as conserved quantities. If we choose the parameter appropriately for one of our proposed discrete SIR models, it conserves the conserved quantities of the SIR model. We also investigate an ultradiscretizable discrete SIR model.
