Rass and Radcliffe draw together in one volume mathematical theory which, until now, has existed only in a large number of papers scattered over many journals. They use rigorous analytic methods to determine the behavior of spatial, deterministic models of certain multi-type epidemic processes where infection is spread by means of contact distribution. The results obtained include the existence of traveling wave solutions, the asymptotic speed of propagation, and the spatial final size. For researchers and graduate students working in mathematical methods in biology. Annotation (c) Book News, Inc., Portland, OR (booknews.com)
