Ryan R. Martin, Heather C. Smith, Shanise Walker
Given a finite poset , a family of elements in the Boolean lattice is induced--saturated if contains no copy of …
Planar Posets that are Accessible from Below Have Dimension at Most 6
Csaba Biró, Bartłomiej Bosek, Heather C. Smith +3
Planar posets can have arbitrarily large dimension. However, a planar poset of height has dimension at most , while a planar poset with minimal elements has dimens…
