   <dcterms:abstract>It was long believed that Massey products in the cohomology of a differential graded associative algebra were determined by the higher operations on a minimal A-infinity model. This was disproved by Buijs, Moreno-Fernández, and Murillo. They also gave sufficient conditions for it to hold. In this talk, we will present two further conditions:&#xd;
&#xd;
- Associative algebras with sparse cohomology.&#xd;
&#xd;
- Algebras over Koszul operads.&#xd;
&#xd;
In the latter case, we define an analogue of triple Massey products which extends the cases previously considered in the literature (associative and Lie algebras).</dcterms:abstract>
