Is anyone familiar with books or papers on perturbation theory for closed levels sets in which the equation for the n-sphere is perturbed? For example, the level set:
[tex]\sum_{i=1}^n x_i^2 + \epsilon p(x_i) = C[/tex]
where [tex]\epsilon[/tex] is a small parameter and [tex]p(x_i)[/tex] is a positive polynomial such as [tex]x_i^4[/tex].
[tex]\sum_{i=1}^n x_i^2 + \epsilon p(x_i) = C[/tex]
where [tex]\epsilon[/tex] is a small parameter and [tex]p(x_i)[/tex] is a positive polynomial such as [tex]x_i^4[/tex].
