It is also known as Legendre -- Fenchel transformation or Fenchel transformation ( after Adrien - Marie Legendre and Werner Fenchel ) .
In mathematics and mathematical optimization , the convex conjugate of a function is a generalization of the Legendre transformation which applies to non-convex functions .
