Bifurcation-sphere stability and full interior series completion
partial Interior / SCC
Statement
Complete the geometric analysis of the perturbed Kerr interior all the way to the bifurcation sphere and global Cauchy-horizon structure.
Mathematical prerequisites
Double-null interior geometry; regularity propagation to bifurcate sets; characteristic PDE methods.
Why it matters
The interior picture is not complete until the full boundary geometry is understood, not just a local Cauchy-horizon segment.
Completion criteria
A complete answer must classify all future interior boundary pieces and prove regularity statements up to the bifurcation region.
Implications if solved
Would finish the geometric part of the vacuum rotating interior program.
