Evolution Equations and Lagrangian Coordinates

Booknews

Of the two basic methods for describing the motions of continua, discusses the Legrange approach, in which the observer follows the path of particles, assuming all parameters of the motion to be functions of time and the initial positions of the particles. The method is sometimes preferable in dealing with the motions of continua involving free boundaries that are previously unknown. Presents insights into the algebraic and numerical aspects that the authors have developed at the Russian Academy of Sciences in Novosibirsk, and applies them to the Verigin problem, equivalence transformations of evolution equations, one-dimensional parabolic equations, and parabolic equations in several space dimensions.
