Kaplansky Density and Kadison Transitivity Theorems for Irreducible Representations of Real C^-Algebras

引用

Acta Mathematica Sinica,English Series 2007年第10期23卷 1827-1832页

作者： jeffrey L.BOERSEMA Department of Mathematics Seattle UniversitySeattleWA 98122USA

We prove analogs of the Kaplansky Density Theorem and the Kadison Transitivity Theorem for irreducible representations of a real C＊-algebra on a real Hilbert space. Specifically, if a C＊-algebra is acting irreducibly on a real Hilbert space, then the Hilbert space has either a real, complex, or quaternionic structure with respect to which the density and transitivity theorems hold.
