Download or read book Lecture Notes on Geometrical Aspects of Partial Differential Equations written by V V Zharinov and published by World Scientific. This book was released on 1992-03-26 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the properties of nonlinear systems of PDE with geometrical origin and the natural description in the language of infinite-dimensional differential geometry. The treatment is very informal and the theory is illustrated by various examples from mathematical physics. All necessary information about the infinite-dimensional geometry is given in the text.
