Vertex Contact Graphs of Paths on a Grid,y disjoint grid-paths. Adjacencies are represented by contacts between an . of one grid-path and an . of another grid-path. Defining . if the path of . ends on path of . we obtain an orientation on . from a VCPG. To get hand on the bends of the grid path the orientation is not enough. We therefore c

Deciding the Bell Number for Hereditary Graph Properties,e speed of hereditary graph properties to the Bell number . and provides a partial characterisation of the family of minimal classes whose speed is at least .. In the present paper, we give a complete characterisation of this family. Since this family is infinite, the decidability of the problem of

Boxicity and Separation Dimension,n . in which all the vertices in one edge precede those in the other. The cardinality of a smallest such family of permutations for . is called the . of . and is denoted by .. Equivalently, . is the smallest natural number . so that the vertices of . can be embedded in . such that any two disjoint e
