Duality and the Duality Controversy
2011The technique of pole and polar is applied to the theorems of projective geometry described in Chapter 3, and it shown that new theorems result. This leads to the idea of a duality in the new geometry, in which the words point and line are interchanged, and the adjectives collinear and concurrent are interchanged. This theory can be extended to yield a

Fehchel duality from LP duality
Mathematische Operationsforschung und Statistik. Series Optimization, 1980Let f closed - grcoer convex functions. We derive Fenchel duality theorem from LP duality by finding polyhedral approximations f iand g ito f iand g ito fand gsuch that (under the conditions of the Fenchel theorem). (i)the problems to find inf {f i–g iand sup correspond to a pair of mutually dual linear programs. (ii)inf{f i–g i}→{f–g i} and sup . (iii)

For a commutative ring R we discuss uniqueness of functorial dualities of the category L R of locally compact R-modules (i. e. involutive contravariant endofunctors of L R). Roeder proved that in case R is the ring of integers (i. e. for locally compact abelian groups) Pontryagin duality is the unique functorial duality.
