Regularity of joint-meet ideals of distributive lattices


Let LL be a distributive lattice and R(L)R(L) the associated Hibi ring. We compute \reg R(L) when LL is a planar lattice and give a lower bound for \reg R(L) when LL is non-planar, in terms of the combinatorial data of L.L. As a consequence, we characterize the distributive lattices LL for which the associated Hibi ring has a linear resolution
