%0 Journal Article %T Media theory: representations and examples %A Sergei Ovchinnikov %J Mathematics %D 2005 %I arXiv %X In this paper we develop a representational approach to media theory. We construct representations of media by well graded families of sets and partial cubes and establish the uniqueness of these representations. Two particular examples of media are also described in detail. %U http://arxiv.org/abs/math/0512282v1
