Two difference equations or dynamcial system are said
to be *identical* if the infinite set of algebraic equation that
they represent are identical. They represent the same set of equations.

**Example**:

_{ }
for _{ }
is identical to _{ }
for _{ }
because both dynamical system generate the same sequence for the same
initial value. If _{ }
, they will generate a sequence of_{ }
