Symmetric bundles and representations of Lie triple systems
Autor: Manon Didry, Wolfgang Bertram
Publikováno v: J. Gen. Lie Theory Appl. 3, no. 4 (2009), 261-284
We define symmetric bundles as vector bundles in the category of symmetric spaces; it is shown that this notion is the geometric analog of the one of a representation of a Lie triple system. We show that such a bundle has an underlying reflection spa

Projective completions of Jordan pairs
Autor: Karl-Hermann Neeb, Wolfgang Bertram
Publikováno v: Journal of Algebra. 277:474-519
We prove that the projective completion (X+,X−) of the Jordan pair ( g 1 , g −1 ) corresponding to a 3-graded Lie algebra g = g 1 ⊕ g 0 ⊕ g −1 can be realized inside the space F of inner 3-filtrations of g in such a way that the remoteness

From linear algebra via affine algebra to projective algebra
Autor: Wolfgang Bertram
Publikováno v: Linear Algebra and its Applications. 378:109-134
We introduce an algebraic formalism, called “ affine algebra”, which corresponds to affine geometry over a field or ring K in a similar way as linear algebra corresponds to affine geometry with respect to a fixed base point. In a second step, we

The geometry of null systems, Jordan algebras and von Staudt's theorem
Autor: Wolfgang Bertram
Publikováno v: Annales de l’institut Fourier. 53:193-225
Nous caracterisons une classe importante de geometries projectives generalisees (X, X') par les proprietes equivalentes suivantes : (1) (X, X') admet une polarite nulle centrale; (2) (X,X') admet une polarite interieure; (3) (X, X') est associee a un

Conformal group and fundamental theorem for a class of symmetric spaces
Autor: Wolfgang Bertram
Publikováno v: Mathematische Zeitschrift. 233:39-47
Using a geometric approach, we define and investigate the conformal group of a symmetric space with twist. In the non-degenerate case we characterize this group by a theorem generalizing the fundamental theorem of projective geometry.

Hardy spaces and analytic continuation of Bergman spaces
Autor: Wolfgang Bertram, Joachim Hilgert
Publikováno v: Bulletin de la Société mathématique de France. 126:435-482
Nous introduisons une famille d'espaces de Bergman ponderes associee a un espace symetrique compactement causal, et nous examinons la relation entre l'espace de Hardy correspondant et le prolongement analytique de cette famille. Pour une classe impor

Un théorème de Liouville pour les algèbres de Jordan
Autor: Wolfgang Bertram
Publikováno v: Bulletin de la Société mathématique de France. 124:299-327
Un theoreme classique de Liouville decrit les transformations conformes d'un espace vectoriel euclidien. Nous generalisons ce theoreme aux algebres de Jordan simples (et non isomorphes a R ou C). La premiere partie de la preuve est purement algebriqu

Torsors and ternary Moufang loops arising in projective geometry

We give an interpretation of the construction of torsors from preceding work (Bertram, Kinyon: Associative Geometries. I, J. Lie Theory 20) in terms of classical projective geometry. For the Desarguesian case, this leads to a reformulation of certain
