Abstract
Zombies are a popular figure in pop culture/entertainment and they are usually
portrayed as being brought about through an outbreak or epidemic. Consequently,
we model a zombie attack, using biological assumptions based on popular zombie
movies. We introduce a basic model for zombie infection, determine equilibria and
their stability, and illustrate the outcome with numerical solutions. We then refine the
model to introduce a latent period of zombification, whereby humans are infected, but
not infectious, before becoming undead. We then modify the model to include the
effects of possible quarantine or a cure. Finally, we examine the impact of regular,
impulsive reductions in the number of zombies and derive conditions under which
eradication can occur. We show that only quick, aggressive attacks can stave off the
doomsday scenario: the collapse of society as zombies overtake us all.

最后一句比较寒。。。
The zombies have grabbed quite a lot of attention. And rightly so, because who doesn't love the flesh-eating undead? A surprising number of people have emailed me to tell me that the model doesn't include the killing of the zombies (it does, in the impulsive eradication section) or that zombies don't come back to life when you kill them (I'm sorry, but they do; Shaun hits one with his car in Shaun of the Dead and then it comes back to life). The fact that I can have this kind of discussion about my academic work thrills me to bits. Except for that one guy who asked, apparently in all seriousness, if I'd help him create a zombie virus. Now that's scary.
