Special Issue “Symmetries of Differential Equations: Frames, Invariants and Applications”

The Guest Editors for this special issue are

Niky Kamran (McGill University, Canada)
Gloria Mari Beffa (University of Wisconsin, USA)
Willard Miller (University of Minnesota, USA)
Guillermo R. Sapiro (University of Minnesota, USA)

The special issue will be in honor of the 60th Birthday of Peter Olver, and is in conjunction with the conference “Symmetries of Differential Equations: Frames, Invariants and Applications”.

• symmetries of differential equations and variational problems;
• moving frames for Lie groups and Lie pseudo-groups;
• invariant theory, differential invariants, and generalizations;
• solitons, integrable systems, geometric flows;
• calculus of variations and the variational bicomplex;
• Hamiltonian systems and Poisson structures;
• applications to image processing, fluid mechanics, and elasticity;
• Cartan theory of differential forms and equivalence problems.

Papers are welcome for this issue both from the conference participants and from other authors whose work fits into the topics.

How to Submit an Article to the Issue.

Both original research articles and review papers will be considered (not published or considered for publication elsewhere).

There is no limit to the length of an article. Deadline for paper submission is September 30, 2012.

All articles will go through the standard peer reviewing procedure of SIGMA.

If you have your paper ready earlier than the deadline, we encourage you to send it now. We will start the reviewing process and publish the paper promptly after the positive publication decision. The paper will be indexed in the relevant databases as soon as it is published without waiting for completion of the special issue.
