Pseudo–groups, Moving Frames, and Differential Invariants

چکیده
We survey recent developments in the method of moving frames for infinite-dimensional Lie pseudo-groups. These include a new, direct approach to the construction of invariant Maurer–Cartan forms and the Cartan structure equations for pseudo-groups, and new algorithms, based on constructive commutative algebra, for establishing the structure of their differential invariant algebras.

Recursive Moving Frames for Lie Pseudo-Groups
This paper introduces a new, fully recursive algorithm for computing moving frames and differential invariants of Lie pseudo-group actions. The recursive method avoids unwieldy symbolic expressions that complicate the treatment of large scale applications of the equivariant moving frame method. The development leads to novel results on partial moving frames, structure equations, and new differe...
متن کاملMoving Frames and Differential Invariants for Lie Pseudo-groups
We survey a recent extension of the moving frames method for infinite-dimensional Lie pseudo-groups. Applications include a new, direct approach to the construction of Maurer–Cartan forms and their structure equations for pseudogroups, and new algorithms, based on constructive commutative algebra, for uncovering the structure of the algebra of differential invariants for pseudogroup actions.
متن کاملMoving Frames for Pseudo–Groups. II. Differential Invariants for Submanifolds
This paper is the second in a series that develops a theory of moving frames for pseudogroup actions. In this paper, we define a moving frame for free pseudo-group action on the submanifolds, illustrated by explicit examples. Our methods, based on the consequential moving frame connection, provides an effective means for explicitly determining complete systems of differential invariants and inv...
متن کاملMoving Frames for Pseudo–Groups. I. The Maurer–Cartan Forms
This paper begins a series devoted to developing general and practical theory of moving frames for infinite-dimensional Lie pseudo-groups. In this first, preparatory part, we present a new, direct approach to the construction of invariant Maurer–Cartan forms and the Cartan structure equations for a pseudo-group. Our approach is completely explicit and avoids reliance on the theory of exterior d...
متن کاملMoving Frames for Lie Pseudo–Groups
We propose a new, constructive theory of moving frames for Lie pseudo-group actions on submanifolds. The moving frame provides an effective means for determining complete systems of differential invariants and invariant differential forms, classifying their syzygies and recurrence relations, and solving equivalence and symmetry problems arising in a broad range of applications.
