Ebook: Analytical and numerical methods for wave propagation in fluid media

Mathematical aesthetics is not usually discussed as a separate discipline, even though it is reasonable to suppose that the foundations of physics lie in mathematical aesthetics. This book presents a list of mathematical principles that can be classified as "aesthetic" and shows that these principles can be cast into a nonlinear set of equations. Then, with this minimal input, the book shows that one can obtain lattice solutions, soliton systems, closed strings, instantons and chaotic-looking systems as well as multi-wave-packet solutions as output. These solutions have the common feature of being nonintegrable, ie. the results of integration depend on the integration path. The topic of nonintegrable systems is discussed Ch. 1.
