Streszczenie
A classical result of singularity theory states that the spectrum of an isolated hypersurface singularity is symmetric with respect to $n/2$, where $n$ is the dimension of the enclosing space. We prove a similar result for the Jordan–Hölder composition series of the $(a,b)$-module associated to an isolated hypersurface singularity.
