**Publisher**: University Of Chicago Press 2008**ISBN/ASIN**: 0226077942**ISBN-13**: 9780226077949**Number of pages**: 219

**Description**:

The authors present the results of their ongoing development of a theory of the geometry of differential equations, focusing especially on Lagrangians and PoincarĂ©-Cartan forms. They also cover certain aspects of the theory of exterior differential systems, which provides the language and techniques for the entire study.
