Duality in Mathematics
In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of A is B, then the dual of B is A.

Involution
In mathematics, an involution, or an involutory function, is a function f that is its own inverse.
f ( f ( x ) ) = x f(f(x))=x
