Cohomology rings and nilpotent quotients of real and complex arrangements
Daniel Matei, Alexander I. Suciu
For an arrangement with complement X and fundamental group G, we relate the truncated cohomology ring, H^{<=2}(X), to the second nilpotent quotient, G/G_3. We define invariants of…

Homotopy types of complements of 2-arrangements in R^4
Daniel Matei, Alexander I. Suciu
We study the homotopy types of complements of arrangements of n transverse planes in R^4, obtaining a complete classification for n <= 6, and lower bounds for the number of homotop…
