Abstract: Abstract This final chapter is devoted to duality, the dual variety and the conormal scheme of an embedded projective variety are given as applications. Reflexivity and biduality are studied, in particular duality of hyperplane sections and projections. An application we present here is a very nice theorem of Hefez and Kleiman. Finally we give a brief presentation of some further results on duality and reflexivity.
