We define the PBW basis for Yangian Double and compute Hopf pairing for elements of this basis. We derive the multiplicative formula for the universal $\mathrm{R}$-matrix of the Yangian Double $DY(Q_n)$ from these Hopf pairing formulas. We also describe a general construction of the Twisted Drinfeld Yangians. Язык доклада: английский
