The Malcev completion of complex braid groups

Ivan Marin

In this short note we provide an alternative proof of a theorem of Kapovich and Millson about the Malcev completion of an arbitrary Artin group, and determine the Malcev completion…

Randomized simplicial sets

Ivan Marin

We construct new geometric realizations of simplicial and pre-simplicial sets where the standard -simplex, viewed as the space of probability measures on elements, is repl…

Parabolic subgroups of complex braid groups

Juan González-Meneses, Ivan Marin

In this paper we introduce a class of `parabolic' subgroups for the generalized braid group associated to an arbitrary irreducible complex reflection group, which maps onto the col…

Cohomology of quasi-abelianized braid groups

Filippo Callegaro, Ivan Marin

We investigate the rational cohomology of the quotient of (generalized) braid groups by the commutator subgroup of the pure braid groups. We provide a combinatorial description of…

Hecke algebras of normalizers of parabolic subgroups

Thomas Gobet, Ivan Marin

In the context of Hecke algebras of complex reflection groups, we prove that the generalized Hecke algebras of normalizers of parabolic subgroups are semidirect products, under sui…

On the largest representation in type

Ivan Marin

In this technical note, we complete the PhD work of A. Esterle about determining the image of any Artin group of finite Coxeter type inside the associated Hecke algebra over a fini…
