Newton polyhedra of discriminants of projections
Alexander Esterov
For a system of polynomial equations, whose coefficients depend on parameters, the Newton polyhedron of its discriminant is computed in terms of the Newton polyhedra of the coeffic…
Quasi-Kähler groups, 3-manifold groups, and formality
Alexandru Dimca, Stefan Papadima, Alexander I. Suciu
In this note, we address the following question: Which 1-formal groups occur as fundamental groups of both quasi-Kähler manifolds and closed, connected, orientable 3-manifolds. We…
Characteristic varieties and logarithmic differential 1-forms
Alexandru Dimca
We introduce in this paper a hypercohomology version of the resonance varieties and obtain some relations to the characteristic varieties of rank one local systems on a smooth quas…
