ИСТИНА

Buchstaber conjectured that the cohomology of Landweber-Novikov algebra is generated by two elements with respect to non-trivial Massey products. Fukhs, Feigin and Retakh found realisations of all basic cocycles by means of trivial Massey products. Later, Buchstaber's PhD student Artelnykh found some non-trivial realisations but not for all cohomology. We will discuss a recent progress in the direction of the whole answer.
