The non-semi-symmetric case allows essentially two distinct geometries in addition to the 3-symmetric spaces, without a Kahlerian counterpart.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Lie algebraPara-Kahler structureSemi-symmetricRecurrent curvatureSimply harmonicjournal article10.1142/S0129167X23501069restricted access
