Название: Exterior differential systems
Авторы: Bryant R.L., Chern S.S., Gardner R.B.
Аннотация:
A treatment of both the general theory and various applications of exterior differential systems, i.e. systems of equations on a manifold defined by equating to zero a number of exterior differential forms. The volume particularly studies the integral manifolds, that is, submanifolds satisfying all the equations of the system.
