Farkas' Lemma and Morphism Duality

Abstract

In this paper we investigate the class NP cap co-NP (or the class of problems permitting a good characterisation) from the point of view of morphisms of oriented matroids. We prove several morphism duality theorems for oriented matroids. These generalize LP-duality (in form of Farkas' Lemma) and Minty's Painting Lemma. Moreover, we characterize all morphism duality theorems, thus proving the essential unicity of Farkas' Lemma.
