Yangians and universal enveloping algebras

In terms of the algebras $U(\mathfrak{gl}(n))$, $n=1,2,\dots$ an algebra A is constructed, which yields both a realization of the Yangians $Y(\mathfrak{gl}(m))$ and the “right” version of the universal enveloping algebra for certain classical infinite-dimensional Lie algebras. Bibl. – 9.
