In general, a point process is a random variable

N

from some probability space

(\Omega,\mathcal{F},P)

to a space of counting measures on

{\bf R}

, say

(M,\mathcal{M})

. So each

N(\omega)

is a measure which gives mass to points

\ldots < X_{-2}(\omega) < X_{-1}(\omega) < X_0(\omega) < X_1(\omega) < X_2(\omega) < \ldots

{\bf R}

(here the convention is that

X_0 \leq 0

. The

X_i

are random variables themselves, called the

points of

N

The intensity of a point process is defined to be

\lambda_N = {\bf E}[N(0,1]].

There are many different possible point processes, but the Poisson point process with intensity

\lambda

is the one for which the number of points in an interval

(0,t]

has a Poisson distribution with parameter

\lambda t

P[N(0,t] = k] = \frac{(\lambda t)^k e^{-\lambda t}}{k!}

and which is stationary. Stationarity is a little more involved to go into here, but in this context you can think of it as meaning that the measure of two different intervals of equal length is the same, thus

P[N(s,s+t] = k] = \frac{(\lambda t)^k e^{-\lambda t}}{k!}, \ \ \forall s.
