Suciu's Conjecture on hyperplane arrangements

Marian Aprodu, Gavril Farkas, Claudiu Raicu +1

We prove that the resonance of any hyperplane arrangement is separable. Using the main result from arXiv:2512.10160 this proves Suciu's conjecture on the fundamental group of every…

Profinite completions and cohomology jump loci

Alexander I. Suciu

Let be a connected finite-type CW-complex with fundamental group . We show that the profinite completion determines the cohomology jump loci $\mathcal{V}^q_s(X…

Groups associated to 1-minimal models for binomial -algebras

Richard D. Porter, Alexander I. Suciu

We give an explicit, cochain-level algebraic model for the pronilpotent completion of a group with finitely generated first cohomology. To each binomial -dga over…

Twisted homology jump loci, twisted Alexander polynomials, and -invariants

Yongqiang Liu, Alexander I. Suciu

We introduce the twisted homology jump loci of a space : the jump loci for homology with coefficients in rank-one local systems, twisted by a fixed finite-dimensional representa…

Highly connected non-formal Milnor fibers via polyhedral products

Alexander I. Suciu

We show that the realization theorem of Fernández de Bobadilla, which identifies the Milnor fiber of a weighted-homogeneous polynomial with the complement of a germ of analytic set…

Koszul modules, holonomy Lie algebras, and resonance of groups and CDGAs

Alexander I. Suciu

We develop a Koszul-theoretic framework for comparing classical Alexander-type invariants with infinitesimal invariants arising from finite-type commutative differential graded alg…
