报告内容:One of the important problems in many branches of science and industry, e.g., pandemic, ecology, biology, engineering, ffnance, social science, is the speciffcation of the stochastic process governing the behaviour of an underlying quantity. We here use the term underlying quantity to describe any interested object whose value is known at present but is liable to change in the future. In this talk, we will explain how the ordinary differential equations (ODEs) are not enough to model the underlying stochastic quantity and why stochastic differential equations (SDEs) appear naturally. Several well-known SDE models will be presented including the Nobel prize winning model in ffnance, stochastic SIS epidemic model, stochastic Lotka-Volterra model. We will then show how SDE models differ signiffcantly from ODE models and highlight how we can make use of noise in various applications including stochastic stabilisation, volatility effect in ffnance, population explosion suppressed by noise, extinction of infected individuals by noise in epidemic.
