Abstract / Description of output
We use purely topological methods to prove the semicontinuity of the mod
2 spectrum of local isolated hypersurface singularities in C^{n+1}, using Seifert forms of high-dimensional non-spherical links, the Levine–Tristram signatures and the generalized Murasugi–Kawauchi inequality.
