The category of $E_{\infty}$ -coalgebras, the $E_{\infty}$ -coalgebra structure on the homology, and the dimension completion of the fundamental group

Grigory Rybnikov

We study a special type of $E_{\infty}$ -operads that govern strictly unital $E_{\infty}$ -coalgebras (and algebras) over the ring of integers. Morphisms of coalgebras over such an opera…

On the fundamental group of the complement of a complex hyperplane arrangement

Grigory Rybnikov

We construct two combinatorially equivalent line arrangements in the complex projective plane such that the fundamental groups of their complements are not isomorphic. The proof us…
