WebDetailed Description. interface to a 2.5d polygon of arbitrary complexity. The DM polygon object can handle arbitrary nested polygons (often called multi part polygons). The implementation is based on the CGAL nef polygons, a 2d polyhedron representation. Hence, positive regions (=part of the polygon) may contain an arbitrary number of … WebThis expository article explores the connection between the polar duality from polyhedral geometry and mirror symmetry from mathematical physics and algebraic geometry. Topics discussed include duality of polytopes and cones as well as the famous quintic threefold and the toric variety of a reflexive polytope. WebThe main purpose of this paper is to give a simple and non-combinatorial proof of the toric Mori theory. Here, the toric Mori theory means the (log) Minimal Model Program (MMP, for short) for toric varieties. We minimize the arguments on fans and their decompositions.
