Riemann’s Philosophy of Geometry and Kant’s Pure Intuition [PDF]

open access: yesOrganon F
The aim of this paper is twofold: first to explicate how Riemann’s philosophy of geometry is organized around the concept of manifold. Second, to argue that Riemann’s philosophy of geometry does not dismiss Kant’s spatial intuition.

KdV-charged black holes

open access: yesJournal of High Energy Physics, 2020
We construct black hole geometries in AdS3 with non-trivial values of KdV charges. The black holes are holographically dual to quantum KdV Generalized Gibbs Ensemble in 2d CFT.

Experience and Universal Judgements: William Kingdon Clifford and Non-Euclidean Geometries

open access: yesRevue LISA, 2009
La pensée de W. K. Clifford se distingue par un questionnement radical de la valeur de la connaissance humaine. Fondée sur une doctrine exclusivement empiriste, elle n’adhère cependant pas pleinement aux conceptions de l’expérience alors défendues par ...

Non-Euclidean Laguerre Geometry and Incircular Nets [PDF]

open access: yesSpringerBriefs in Mathematics, 2020
Classical (Euclidean) Laguerre geometry studies oriented hyperplanes, oriented hyperspheres, and their oriented contact in Euclidean space. We describe how this can be generalized to arbitrary Cayley-Klein spaces, in particular hyperbolic and elliptic ...
