Definition:Forward Shift Operator

Definition
Let $T = \sequence {z_t}$ be a discrete time series.

The forward shift operator $F$ is defined as:
 * $\forall t: \map F {z_t} = z_{t + 1}$

Also denoted as
The forward shift operator $F$ can also be seen denoted as $B^{-1}$, that is, the inverse of the backward shift operator.
