Definition of the Poisson process.


efinition

The Poisson process $N_{t}$ is a piecewise continuous non decreasing random process that takes values in the consecutive positive integers. For any $t$ we have MATH MATH MATH In addition, for any $t>0$ , $N_{t+}-N_{t-}$ is independent from MATH and for any $h>0$ , $N_{t+h}-N_{t}$ is distributed as $N_{h}$ . At the jump times we define the process to be continous on the right.

According to the definition, MATH for some number $\lambda$ and infinitesimal $dt$ . The number $\lambda$ is called "intensity" of Poisson process.

In the applications of the following chapters we will be interested in the time $\tau$ of the first Poisson jump. We introduce the notation $\QTR{cal}{H}_{t}$ for the filtration generated by the process MATH . The following properties directly follow from the definitions:

MATH (Poisson property 1)
