Isoperimetric functional inequalities via the maximum principle: the exterior differential systems approach | Paata Ivanisvili
; Alexander Volberg
; | Date: |
21 Nov 2015 | Abstract: | The goal of this note is to give the unified approach to the solutions of a
class of isoperimetric problems by relating them to the exterior differential
systems studied by R.~Bryant and P.~Griffiths. In this note we list several
classical by now isopereimetric inequalities which can be proved in a unified
way. This unified approach reduces them to the so-called exterior differential
systems studied by Robert Bryant and Phillip Griffiths. To the best of our
knowledge, this is the first article where this connection is used.
