Infinitely divisible projective representations of the Lie algebras

Mathematical Proceedings of the Cambridge Philosophical Society, 1972
Infinitely divisible group representations were first defined by Streater(1) as an important concept closely related to continuous tensor product. Araki(2) analysed the factorizable representations of Lie groups and obtained a generalization of the Levy–Khinchine formula.

Fundamental theorem of projective geometry in Lie modules and algebras

Journal of Soviet Mathematics, 1988
Es ist wohlbekannt, daß jeder Automorphismus eines projektiven Raumes über einem Schiefkörper K (oder des zugehörigen Unterraumverbandes) durch eine semilineare Abbildung des zugehörigen K-Vektorraumes X induziert werden kann (Hauptsatz der projektiven Geometrie). Verf.

Direct Integral Decomposition of Two-Projection Algebras and Fiberwise Lie Algebra Structure of su(2)

We study the von Neumann algebra \mathcal{M} = \{P,Q\}'' generated by two orthogonal projections on a separable Hilbert space. Using the Halmos direct integral decomposition in the sense of Dixmier and Takesaki, we show that \mathcal{M} decomposes into abelian parts and a measurable field of copies of M_2(\mathbb{C}).
