Symmetry Analysis and Exact Solutions of Equations of Nonlinear Mathematical Physics formatIsbn:Softcover - 9789048142446 Das vorliegende Werk befasst sichby spin or (spin s = 1 2) field equations is emphasized because their solutions can be used for constructing solutions of other field equations insofar as fields with any spin may be constructed from spin s = 1 2 fields. A brief account of the main ideas of the book is presented in the Introduction. The book is largely based on the authors' works [55 109, 176 189, 13 16, 7* 14*,23*, 24*] carried out in the Institute of Mathematics, Academy of Sciences
