Triangulability of p-algebras
of a Lie p-algebra L is discussed. Necessary and sufficient conditions are determined
that the maximal triangulable subalgebras of the p-subalgebras of L be the
normalizers of their maximal nilsubalgebras. The maximal triangulable ideals of L
are located within a specific interval of a canonical ascending chain of ideal
terminating in the solvable radical of L.
