Geometry associated with semisimple flat homogeneous spaces
Geometry associated with semisimple flat homogeneous spaces
Our object is Cartan connections with semisimple flat homogeneous spaces as standard spaces. We study these from the viewpoint of <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="upper G"> <mml:semantics> <mml:mi>G</mml:mi> <mml:annotation encoding="application/x-tex">G</mml:annotation> </mml:semantics> </mml:math> </inline-formula>-structures of second order. This allows us especially to treat classical projective and conformal connections in the unifying …
