The book contains Proceedings of the 2nd German-Korean Workshop on Algebra and Topology, which was held at Pusan National University, Korea, in August 2000. The main aim of this workshop was to stimulate cooperation between Germany and Korea. The proceedings present 14 articles based on selected lectures delivered at the workshop. We can say that lectures were focused on low dimensional topology. In the proceedings, there are also several contributions concerning group theory but they always deal (maybe with one exception) with group theoretical problems arising in low dimensional topology. All articles are very carefully written, and several of them contain a survey of the recent research in relevant directions (e.g., Recent developments in the theory of Fuchsian and Kleinian groups, Quadratic equations in free groups and topological applications, Colourings of polyhedra and hyperelliptic 3-manifolds, Survey on dimension subgroup problem). The collection will be of interest to topologists working in low dimensional topology and for group theorists cooperating with them.
