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

Liam Ashton, Manuel Rivera

The paper introduces double Lie bimodules and uses them to decompose the Goldman‑Turaev Lie bialgebra of a surface when the surface is cut along a simple separating closed curve.

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…

Comparing dg category models for path spaces via -functors

Manuel Rivera, Yi Wang

We construct a many-object dual version of Chen's iterated integral map. For any topological space X, the construction takes the form of an A-infinity functor between two dg catego…

An algebraic model for the constant loops map

Luis Fernandez, Manuel Rivera, Thomas Tradler

For any simplicial complex with a total ordering of its vertices, one can construct a chain complex generated by necklaces of simplices in , which co…

Koszul duality and Calabi-Yau structures

Julian Holstein, Manuel Rivera

We show that Koszul duality between differential graded categories and pointed curved coalgebras interchanges smooth and proper Calabi-Yau structures. This result is a generalizati…

Equivariant Homotopy Theory via Simplicial Coalgebras

Sofía Martínez Alberga, Manuel Rivera

Given a commutative ring , a --equivalence is a continuous map of spaces inducing an isomorphism on fundamental groups and an -homology equivalence between universal…
