Dual Swap Operator
If we combine the Dual Operator and the Dual Derivative Operator we can build a dual swap operator by:
\[ (\epsilon + d\epsilon) (a + \epsilon\, b) = b + \epsilon \, a \]
If we combine the Dual Operator and the Dual Derivative Operator we can build a dual swap operator by:
\[ (\epsilon + d\epsilon) (a + \epsilon\, b) = b + \epsilon \, a \]
