Ebook: Introduction to the $h$-Principle

Eliashberg and Mishachev (credentials not listed) discuss two methods for proving the h-principle: holonomic approximation and convex integration. Applications to symplectic and contact geometry are emphasized. A brief text, the book is suited for a graduate-level course on geometric methods for solving partial differential equations and inequalities. Numerous diagrams illustrate the principles and concepts described in the text.
