Exterior Differential Systems and the Calculus of Variations by Phillip A. Griffiths
English | PDF | 1983 | 348 Pages | ISBN : 0817631038 | 14.6 MB
This monograph is a revised and expanded version of lecture notes from a class given at Harvard University, Nankai University, and the Graduate School of the Academia Sinica during the academic year 1981-82. The objective was to present the formalism, together with numerous illustrative examples, of the calculus of variations for functionals whose domain of definition consists of integral manifolds of an exterior differential system. This includes as a special case the Lagrange problem of analyzing classical functionals with arbitrary (i.e., nonholonomic as well as holonomic) constraints. A secondary objective was to illustrate in practice some aspects of the theory of exterior differential systems. In fact, even though the calculus of variations is a venerable subject about which it is hard to say something new, (l) we feel that utilizing techniques from exterior differential systems such as Cauchy characteristics, the derived flag, and prolongation allows a systematic treatment of the subject in greater generality than customary and sheds new light on even the classical Lagrange problem.

Product Details Every awesome character needs an awesome world to live in! In this course, Professional illustrator Jake Parker, along with Will Terry, teaches how to design appealing and believable exterior environments.
Environment design is about more than just making a cool landscape. It's key component of good visual storytelling!  The environment describes the world your character lives in. Where does it take place? Why does it take place there? How does it shape your character's point of view? It can set the whole tone and mood for the story.  Characters don't just exist in a void. At some point, they need to go out into the world and live their stories!  In this course, Jake Parker, with help from Will Terry, will guide you through the process of designing appealing exterior environments.
