The papers in this book represent the current state of knowledge in group theory. It includes articles of current interest written by such scholars as S.M. Gersten, R.I. Grigorchuk, P.H. Kropholler, A. Lubotsky, A.A. Razborov and E. Zelmanov. The contributed articles, all refereed, cover a wide range of topics in combinatorial and geometric group theory. The volume will be indispensable to all researchers in the area.

The volume starts with comparative reservoir limnology and deals with problems relating to tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also...
