Explicit Cayley triples in real forms of \(G_2\), \(F_4\), and \(E_6\). (English) Zbl 1040.17004
Earlier the author classified nilpotent adjoint orbits of real simple noncompact groups [J. Algebra 112, 503–524 (1988; Zbl 0639.17005); J. Algebra 116, 196–207 (1988; Zbl 0653.17004)]. Here he classifies \(G_2, F_4,E_6\) by giving explicit representatives for each orbit as linear combinations of vectors from a suitably normalized Chevalley basis of the complexified Lie algebra. Each representative is embedded in a Cayley triple; square roots in these coefficients are to be used.
