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…

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…

Hyperplane arrangements with non-formal Milnor fibers

Alexander I. Suciu

Each complex hyperplane arrangement gives rise to a Milnor fibration of its complement. Building on work of Zuber, we give a combinatorial sufficient condition for th…

Cup-one algebras and 1-minimal models

Richard D. Porter, Alexander I. Suciu

In previous work we introduced the notion of binomial cup-one algebras, which are differential graded algebras endowed with Steenrod -products and compatible binomial opera…

Formality and finiteness in rational homotopy theory

Alexander I. Suciu

We explore various formality and finiteness properties in the differential graded algebra models for the Sullivan algebra of piecewise polynomial rational forms on a space. The 1-f…
