Ak singularity
text:
In mathematics, and in particular singularity theory, an Ak singularity, where k ≥ 0 is an integer, describes a level of degeneracy of a function. The notation was introduced by V. I. Arnold. Let f : R n → R be a smooth function. We denote by Ω the infinite-dimensional space of all such functions. Let diff denote the infinite-dimensional Lie group of diffeomorphisms R n → R n , and diff the infinite-dimensional Lie group of diffeomorphisms R → R . The product group diff × diff acts on Ω
