Abstract:Abstract. We define symmetric spaces in arbitrary dimension and over arbitrary non-discrete topological fields K , and we construct manifolds and symmetric spaces associated to topological continuous quasi-inverse Jordan pairs and -triple systems. This class of spaces, called smooth generalized projective geometries, generalizes the well-known (finite or infinite-dimensional) bounded symmetric domains as well as their "compact-like" duals. An interpretation of such geometries as models of Quantum Mechanics is … Show more

“…Then the involution * lifts to an involution of the projective line AP 1 whose fixed point set is called the Hermitian projective line, see [BeNe05]. Let us give here a slightly modified version of the construction given in loc.…”
Abstract. In the paper "Is there a Jordan geometry underlying quantum physics?" [Be08], generalized projective geometries have been proposed as a framework for a geometric formulation of Quantum Theory. In the present note, we refine this proposition by discussing further structural features of Quantum Theory: the link with associative involutive algebras A and with Jordan-Lie and Lie-Jordan algebas. The associated geometries are (Hermitian) projective lines over A; their axiomatic definition and theory will be given in subsequent work with M. Kinyon [BeKi08].
“…Moreover, it is also shown that G A /G A (p) is a complexification of U A /U A (p), and then these results are translated in terms of homogeneous vector bundles, in the spirit of Theorem 5.8 in [5]. (A complementary perspective on these manifolds can be found in [6].) Section 4 is devoted to exhibit how the above results look like in the (on the other hand well known) case of the algebra A = B(H) and corresponding universal, tautological vector bundles.…”
We investigate geometric properties of Grassmann manifolds and their complexifications in an infinite-dimensional setting. Specific structures of quaternionic type are constructed on these complexifications by a direct method that does not require any use of the cotangent bundles.
