*Title: Ideals and Algebras Associated with Isotone Maps Between Posets *

*Date/Time/Place: 16 March, 11:00, FENS 2008*

*Abstract: *Our main goal is to study the ideal* L(P,Q)* and toric ring *K*[
*P,Q*] whose generators are in bijection to the isotone maps from *P* to *Q*.
We examine the several algebraic properties of* L(P,Q)* including Alexander
duality behavior. The class of algebras *K*[*P,Q*], called isotonian, are
natural generalizations of the so-called Hibi rings. We determine the Krull
dimension of these algebras and for particular classes of posets *P* and *Q*
we show that *K*[*P,Q*] is normal and that their defining ideal admits a
quadratic Grobner basis.
