Polytopes from Posets
|
Poset から作られる多面体としては, まず Stanley [Sta86] により定義された chain polytope と order
polytope がある。その変種も色々定義されている。
- chain polytope と order polytope
- marked chain polytope と marked order polytope [ABS11]
- chain-order polytope [Hib+]
- marked chain-order polytope [FF]
- enriched order polytope tol enriched chain polytope [OT]
他に目についたものを挙げると, 次のようになる。
- poset associahedron [Gal]
- linear order polytope [BKG99; CSS; EY]
- partial order polytope [Fio03]
