Zusammenfassung der Ergebnisse,termine the extremal graphs . with the minimum number of edges such that VCp(.)≥.. Finally, we show a close relation between the VC-dimension of set systems induced by connected sets of vertices and the VC dimension of set systems induced by connected sets of edges; the argument is done via the line graph of the corresponding graph.

VC-dimensions for graphs (extended abstract),termine the extremal graphs . with the minimum number of edges such that VCp(.)≥.. Finally, we show a close relation between the VC-dimension of set systems induced by connected sets of vertices and the VC dimension of set systems induced by connected sets of edges; the argument is done via the line graph of the corresponding graph.

On devising Boolean Routing schemes,also shown that the model deals efficiently with graphs resulting from applying some types of graph compositions, thus resulting in very efficient routing schemes for some classes of networks with regular topology. This is done by considering different significant cost measures of the space efficiency of the schemes considered.

On the isomorphism of graphs with few P4s,rnal nodes correspond to three types of graph operations and the leaves are basic graphs with a simple structure. The paper extends and generalizes results on cographs, ..-reducible graphs, and ..-sparse graphs.

Planarization of graphs embedded on surfaces,re obtained for planarizing vertex sets and for graphs embedded on nonorientable surfaces. Planarizing edge and vertex sets can be found in . time, if an embedding of . on a surface of genus . is given. We also construct an approximation algorithm that finds an . planarizing vertex set of . in . time if no genus-. embedding is given as an input.

Visualizing two- and three-dimensional models of meristematic growth, that simulate patterns described by Lück and Lück [11]. The advantage of these models over their predecessors is that, through the use of a geometric model to determine cell shape, they can be translated into a visual form quite easily in order to animate (and validate) the growth of the meristem.
