Twist Positivity for Lagrangian Symmetries
Olivier Grandjean, Arthur Jaffe, Jon Tyson
We prove twist positivity and positivity of the pair correlation function for combined spatial and internal symmetries of free bosonic Lagrangians. We work in a general setting, ex…
Fundamental strings in Dp-Dq brane systems
J. Froehlich, O. Grandjean, A. Recknagel +1
We study conformal field theory correlation functions relevant for string diagrams with open strings that stretch between several parallel branes of different dimensions. In the fr…
Supersymmetric quantum theory and non-commutative geometry
J. Froehlich, O. Grandjean, A. Recknagel
Classical differential geometry can be encoded in spectral data, such as Connes' spectral triples, involving supersymmetry algebras. In this paper, we formulate non-commutative geo…
Supersymmetric quantum theory, non-commutative geometry, and gravitation. Lecture Notes Les Houches 1995
J. Froehlich, O. Grandjean, A. Recknagel
This is an expanded version of the notes to a course taught by the first author at the 1995 Les Houches Summer School. Constraints on a tentative reconciliation of quantum theory a…
Supersymmetric quantum theory and (non-commutative) differential geometry
J. Froehlich, O. Grandjean, A. Recknagel
We reconsider differential geometry from the point of view of the quantum theory of non-relativistic spinning particles, which provides examples of supersymmetric quantum mechanics…
The Gravitational Sector in the Connes-Lott Formulation of the Standard Model
A. H. Chamseddine, J. Fröhlich, O. Grandjean
We study the Riemannian aspect and the Hilbert-Einstein gravitational action of the non-commutative geometry underlying the Connes-Lott construction of the action functional of the…
