Higher structures on homology groups
Niels Kowalzig, Francesca Pratali
We dualise the classical fact that an operad with multiplication leads to cohomology groups which form a Gerstenhaber algebra to the context of cooperads: as a result, a cooperad w…

Cyclic duality between BV algebras and BV modules
Niels Kowalzig
We show that if an operad is at the same time a cosimplicial object such that the respective structure maps are compatible with the operadic composition in a natural way, then one…

Morita theory for Hopf algebroids, principal bibundles, and weak equivalences
Laiachi El Kaoutit, Niels Kowalzig
We show that two flat commutative Hopf algebroids are Morita equivalent if and only if they are weakly equivalent and if and only if there exists a principal bibundle connecting th…
