Translated-subgroup support conjecture for homotopy characteristic varieties
Translated-subgroup support conjecture for homotopy characteristic varieties
Let be a divisor with isolated non-normal crossings in a sufficiently small ball , and let . The support of the homotopy module in the character torus is defined by the characters at which its associated homology support is nonzero.
Translated-subgroup support conjecture. The support of is a union of translated subgroups of by points of finite order.
This generalizes the corresponding assertion for isolated singularities, where the support is given by the torsion eigenvalues of the Milnor monodromy. The paper presents this as a generalization of the monodromy theorem; no resolution status is supplied.
