5 Questions You Should Ask Before Duality Theorem
Therefore, the solution to the primal is an upper bound to the solution of the dual, and the solution of the dual is a lower bound to the solution of the primal.
In nonlinear programming, the constraints are not necessarily linear. Dually,
Gelfand duality is a duality between commutative C*-algebras A and compact Hausdorff spaces X is the same: it assigns to X the space of continuous functions (which vanish at infinity) from X to C, the complex numbers.
In analysis, problems are frequently solved by passing to the dual description of functions and operators. Using the parlance of category theory, this amounts to a contravariant functor between two categories C and D:
which for any two objects X and Y of C gives a map
That functor may or may not be an equivalence of categories.
