A D-Induced Duality and Its Applications

Abstract: This paper attempts to extend the notion of duality for convex cones, by basing it on a pre-described conic ordering and a fixed bilinear mapping. This is an extension of the standard definition of dual cones, in the sense that the {\em nonnegativity}\/ of the inner-product is replaced by a pre-specified conic ordering, defined by a convex cone $D$, and the inner-product itself is replaced by a general multi-dimensional bilinear mapping. This new type of duality is termed the {\em $D$-induced duality}\/ in the paper. Basic properties of the extended duality, including the extended bi-polar theorem, are proven. Examples are given to show the applications of the new results.
