Khrennikov (mathematical modeling, VU., Sweden) has revised this mathematics textbook on non-Kolmogorov probability models to include new chapters on contextual probability, the inference of probabilities and the representation of probabilities by complex amplitudes. Designed for graduate students and researchers in the fields of cognitive science, economics, finance, psychology and political science, this volume also describes probability models that can be applied to superstring theory and quantum cosmology. The introduction of negative probabilities to generalized frequency probabilities is also discussed. Annotation 2009 Book News, Inc., Portland, OR (booknews.com)
