WebWe consider (classical and generalized) Massey products on the Chekanov homology of a Legendrian knot, and we prove that they are invariant under Legendrian isotopies. We … 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. Ver más Let $${\displaystyle a,b,c}$$ be elements of the cohomology algebra $${\displaystyle H^{*}(\Gamma )}$$ of a differential graded algebra $${\displaystyle \Gamma }$$. If $${\displaystyle ab=bc=0}$$, the Massey product Ver más The complement of the Borromean rings gives an example where the triple Massey product is defined and non-zero. Note the cohomology of the … Ver más • Massey products and its applications - contains many explicit examples • Massey products in the Adams Spectral Sequence - contains references useful for understanding how to do these computations Ver más More generally, the n-fold Massey product $${\displaystyle \langle a_{1,1},a_{2,2},\ldots ,a_{n,n}\rangle }$$ of n elements of $${\displaystyle H^{*}(\Gamma )}$$ is defined to be the set of elements of the form Ver más • Toda bracket Ver más
