My PhD-thesis, written in English. You can get a ps-file of an abstract (both German and English).

You can choose: gzipped PS-file, 290 kB or plain PS-file, 1 MB

- Ends in Digraphs (16 pages, published 1998 in Disc. Math. 184, pp. 225-244)

is a preprint dealing with the ramification structure of one-way infinite paths in digraphs by introducing an end concept which is both a generalization and a refinement of the end concept for the underlying undirected graph. It is a part of my PhD thesis.

- Bibliography (18 pages)

mainly concerning infinite graphs, digraphs, automorphisms of graphs, groups and graphs, Cayley graphs, regular graphs, and transitive graphs

The background of this page may be a little "restless", but it fitted the second part of my PhD thesis too good to not use it here. It depicts the Archimedean tiling of the Euclidean plane where each vertex is surrounded by exactly one triangle, two squares and one hexagon.
