Rings of invariants of special and contact Lie algebras. (English. Russian original) Zbl 0853.17020
Russ. Math. 39, No. 8, 31-36 (1995); translation from Izv. Vyssh. Uchebn. Zaved., Mat. 1995, No. 8, 34-38 (1995).
This is a continuation of the author’s work [Russ. Math. 37, No. 7, 22-26 (1993); translation from Izv. Vyssh. Uchebn. Zaved., Mat. 1993, No. 7, 24-28 (1993; Zbl 0852.17018)] devoted to the determination of the polynomial invariants of the Cartan type algebras $$W_n$$ and $$H_{2n}$$ using restriction from the $$Z$$-forms of these algebras. Here this approach is successfully applied to the types $$S_{n + 1}$$ and $$K_{2n - 1}$$.
Reviewer’s remark: In the translation from the Russian the terminology is often incorrect.
