A t-box representation of a graph encodes each vertex as a box in t-space determined by the (integer) coordinates of its lower and upper corner, such that vertices are adjacent if and only if the corresponding boxes intersect. The boxicity of a graph G is the minirmlm t for which this can be done; e

✦ Synopsis
The m-chain graph of a finite poset is defined as a generalization of the covering graph. 2-chain graphs of posets whose covering graphs are trees are characterized.

## Abstract Usually __dimension__ should be an integer valued parameter. We introduce a refined version of dimension for graphs, which can assume a value [__t__ − 1 ↕ __t__], thought to be between __t__ − 1 and __t__. We have the following two results: (a) a graph is outerplanar if and only if its
A notion of parallelism is defined in finite median graphs and a number of properties about geodesics and the existence of cubes are obtained. Introducing sites as a double structure of partial order and graph on a set, it is shown that all median graphs can be constructed from sites and, in fact, t
The formation of a perfect sequence for a chain-complete poset generalizes the process of dismantling a finite poset by irreducibles. In the finite case, according to a theorem of Duffus and Rival, the end result, or 'core,' is unique up to isomorphism, no matter how the poset is dismantled. For cha
