Non-abelian resonance: product and coproduct formulas
Stefan Papadima, Alexander I. Suciu
We investigate the resonance varieties attached to a commutative differential graded algebra and to a representation of a Lie algebra, with emphasis on how these varieties behave u…
Flat connections and resonance varieties: from rank one to higher ranks
Daniela Anca Macinic, Stefan Papadima, Clement Radu Popescu +1
Given a finitely-generated group and a linear algebraic group , the representation variety Hom has a natural filtration by the characteristic varieties associated to…
Jump loci in the equivariant spectral sequence
Stefan Papadima, Alexander I. Suciu
We study the homology jump loci of a chain complex over an affine \k-algebra. When the chain complex is the first page of the equivariant spectral sequence associated to a regular…
Hyperplane arrangements and Milnor fibrations
Alexander I. Suciu
There are several topological spaces associated to a complex hyperplane arrangement: the complement and its boundary manifold, as well as the Milnor fiber and its own boundary. All…
