su(3) real form
Compact real form of sl(3, C) with its curated integrating groups.
Traceless skew-Hermitian 3 × 3 complex matrices, regarded as a real Lie algebra.
Definition sourcesComplexification
This is the compact real form. The integration links below identify particular global groups with this local algebra.
Reference properties
One algebra, several integrations
A real form is algebraic data over R. The linked group records fix particular connected integrations, and state their global topology separately. Compactness of this real algebra should not be used to infer a particular quotient kernel. [sources]
