Unitary representations of infinite-dimensional pairs \((G,K)\) and the formalism of R. Howe. (English. Russian original) Zbl 0532.22019
Sov. Math., Dokl. 27, 290-294 (1983); translation from Dokl. Akad. Nauk SSSR 269, 33-36 (1983).
Let \(G\) and \(K\) be the inductive limits \(\cup_n \mathrm{U}(n)\) and \(\cup_n \mathrm{SO}(n)\) of the classical groups \(\mathrm{U}(n)\) and \(\mathrm{SO}(n)\). A unitary representation of \(G\) is called “admissible for the pair \((G,K)\)” if its restriction to \(K\) fulfills certain conditions. The author studies and constructs admissible representations for the pair \((G,K)\) and for several other pairs of inductive limits of classical or symmetric groups.
