Undecidability of the quasi-isomorphism problem for semi-free dg algebras via the cobar construction

Manuel Rivera

We explain how the undecidability of the quasi-isomorphism and derived Morita equivalence problems for semi-free finitely presented dg associative algebras follows as an immediate…

Splitting the Goldman-Turaev Lie bialgebra along a simple separating curve

Liam Ashton, Manuel Rivera

We introduce the notion of a double Lie bimodule, consisting of a Lie bialgebra L, a Lie L-bimodule P, and a double Lie bracket on P satisfying suitable compatibility conditions. W…
