Wreath products of cocommutative Hopf algebras
Laurent Bartholdi, Olivier Siegenthaler, Todd Trimble
We define wreath products of cocommutative Hopf algebras, and show that they enjoy a universal property for coalgebra-split extensions, analogous to the Kaloujnine-Krasner theorem…
Distortion of imbeddings of groups of intermediate growth into metric spaces
Laurent Bartholdi, Anna G. Erschler
For every metric space in which there exists a sequence of finite groups of bounded-size generating set that does not embed coarsely, and for every unbounded, increasi…
Homological finiteness properties of wreath products
Laurent Bartholdi, Yves de Cornulier, Dessislava Kochloukova
We study the homological finiteness property FPm of permutational wreath products.
Imbeddings into groups of intermediate growth
Laurent Bartholdi, Anna Erschler
Every countable group that does not contain a finitely generated subgroup of exponential growth imbeds in a finitely generated group of subexponential growth. This produces in part…
