Abstract
Evolution equations with infinite hierarchies of symmetries have been shown to nat- urally arise within the context of geometric, arc-length preserving flows of curves in the plane and in three dimensions. In the following work, a systematic investigation into this phenomenon is conducted for the case of group actions on planar curves. Equivariant moving frames and the variational bicomplex are used. A catalog of results is produced, connecting many invariant curve flows with integrable equations such as Burgers', KdV, mKdV, and Sawada-Kotera. In the last chapter, the techniques are extended to an investigation of the evolution of curvature of 2-dimensional surfaces in 4-dimensional Euclidean space under the Skew-Mean-Curvature flow.
