Equivalence of min–max and max–min variational eigenvalue families
Determine whether the min–max and max–min variational eigenvalue sequences associated with the Krasnoselskii, Drábek, Yang, and $C^2$-spheres constructions (for $p>2$) coincide for all indices and parameters, or construct explicit counterexamples showing they differ.

Are they all the same or is there any example where they are different?
