Ideals in distributive posets

Cyndyma Batueva, Marina Semenova (2011)

Open Mathematics

We prove that any ideal in a distributive (relative to a certain completion) poset is an intersection of prime ideals. Besides that, we give a characterization of n-normal meet semilattices with zero, thus generalizing a known result for lattices with zero.

Incidence structures of type $(p, n)$

František Machala (2003)

Czechoslovak Mathematical Journal

Every incidence structure $𝒥$ (understood as a triple of sets $(G, M, I)$ , $I \subseteq G \times M$ ) admits for every positive integer $p$ an incidence structure $𝒥^{p} = (G^{p}, M^{p}, I^{p})$ where $G^{p}$ ( $M^{p}$ ) consists of all independent $p$ -element subsets in $G$ ( $M$ ) and $I^{p}$ is determined by some bijections. In the paper such incidence structures $𝒥$ are investigated the $𝒥^{p}$ ’s of which have their incidence graphs of the simple join form. Some concrete illustrations are included with small sets $G$ and $M$ .
