Combinatorial Fans, Lattice-ordered Groups, and Their Neighbours: A Short Excursion
Séminaire lotharingien de combinatoire, Tome 47 (2001-2002)
Just like the celebrated dictionary between integral convex geometry and toric varieties bridged until then remote mathematical worlds, the less well-known duality between (certain) lattice-ordered groups and rational polyhedral sets brought combinatorial techniques to bear on the investigation of these abstract algebraic structures. We offer a brief excursion into these relatively new territories, with special emphasis on the novel and admittedly unclear rôle played by order-theoretical considerations.
