In a recent paper Buchstaber and the author introduced a new structure on the cohomology of Hopf algebras in terms of the Buchstaber spectral sequence (Bss). We fully calculate this structure on the cohomology (known for a long time) of the important Hopf subalgebra A(1) of the classical Steenrod algebra A2.
As part of a demonstration ...

We give a correct statement and a complete proof of the criterion obtained in a paper of Grbic-Panov-Theriault-Wu for the face rin k[K] of a simplicial complex K to be Golod over a field k. (The original argument depended on the main result of Berglund and Joellenbeck, which was shown to be false by Katthaen.) We also construct ...

Massey Products in the Cohomology of the Moment-Angle Manifolds Corresponding to Pogorelov Polytopes
E. G. Zhuravleva, Mathematical notes 2019 Vol. 105 No. 4 P. 519–527
Nontrivial Massey products in the cohomology of the moment-angle manifolds corresponding to polytopes in the Pogorelov class are constructed. This class includes the dodecahedron and all fullerenes, i.e., simple 3-polytopes with only 5- and 6-gonal faces. The existence of nontrivial Massey products implies that the spaces under consideration are not formal in the sense of ...

In this paper we illustrate a tight interplay between homotopy theory and combinatorics
within toric topology by explicitly calculating homotopy and combinatorial invariants of toric objects
associated with the dodecahedron. In particular, we calculate the cohomology ring of the (complex and
real) moment-angle manifolds over the dodecahedron, and of a certain quasitoric manifold and of a related
small cover. ...

We discuss a version of the Chevalley--Eilenberg cohomology in characteristic 2, where the alternating cochains are replaced by symmetric ones. ...

We introduce the notions of algebraic and geometric direct families of polytopes and develop a theory of such families. The theory is then applied to the problem of existence of nontrivial higher Massey products in cohomology of moment-angle-complexes. ...

We compute bigraded Betti numbers of graph-associahedra corresponding to maximal non-connected sets of facets. We obtain a criterion of existence of a triple nontrivial strictly defined Massey product of three-dimensional classes in cohomology of a moment-angle manifold over a graph-associahedron. ...

We construct moment-angle-manifolds over 2-truncated cubes having an arbitrarily large prescribed order of a strictly defined nontrivial Massey product in cohomology. We give a criterion of rational formality for moment-angle-manifolds over graph-associahedra. We obtain a sufficient condition for existence of a strictly defined Massey product in cohomology of a moment-angle-complex in terms of vanishing of ...

This paper is a greatly expanded version of [37, Section 9.11]. A series of definitions and results illustrating the thesis in the title (where quasi-formality means vanishing of a certain kind of Massey multiplications in the cohomology) is presented. In particular, we include a categorical interpretation of the “Koszulity implies K(π,1)” claim, discuss the differences between two ...
