Symmetry gaps for higher order ordinary differential equations

Differential Geometry 2022-07-12 v2

Abstract

The maximal contact symmetry dimensions for scalar ODEs of order 4\ge 4 and vector ODEs of order 3\ge 3 are well known. Using a Cartan-geometric approach, we determine for these ODEs the next largest realizable (submaximal) symmetry dimension. Moreover, finer curvature-constrained submaximal symmetry dimensions are also classified.
