Massey products in differential cohomology via stacks

In algebraic topology, the Massey product is a cohomology operation of higher order introduced in (Massey 1958), which generalizes the cup product. The Massey product was created by William S. Massey, an American algebraic topologist.

Web19 de dic. de 2024 · 1 Introduction Higher order Massey products were introduced in [ 10] and generalized in [ 12 ]. These are of fundamental importance not only in the study of differential graded algebras (DGA’s, henceforward) per se, but also in those geometrical contexts where DGA’s play a role.

After a deep reading we found a gap in the proof of Theorem 3.1 of op. cit. and arrived to the conclusion that, as stated in Theorem B, in the A ∞ setting it is also necessary to work with retracts which are adapted to the considered higher Massey product. ethel\\u0027s peak district
