- Title: Weak analysis and MLMC for the system of interacting Poisson Processes
- Abstract: In the simulation of the Biochemical reactions involving small number of particles, the main tool in its simulation study is Poisson process. In this talk I will discuss the methods of simulations for the stochastic jump processes, in particular of the processes generated by finite set of interacting inhomogeneous Poisson Processes. Using random time change representation I will briefly describe the analogue of trapezoidal Euler Maruyama for the inhomogeneous Poisson processes. I will also describe a particular challenge that one must face in the MLMC for the Poisson processes. More specifically, I will explain how the most intuitive coupling fails in the MLMC of the Poisson Processes, and show the asymptotic relationship between the intuitive coupling and the coupling that works.
