Non-Gaussian Expansion of Minkowski Tensors in Redshift Space
The Astrophysical JournalThis paper focuses on extending the use of Minkowski tensors to analyze anisotropic signals in cosmological data, focusing on those introduced by redshift space distortions.

Reconstructing Minkowski space-time [PDF]
, 2005 Minkowski space is a physically important space-time for which the finding an adequate holographic description is an urgent problem. In this paper we develop further the proposal made in hep-th/0303006 for the description as a duality between Minkowski space-time and a Conformal Field Theory defined on the boundary of the light-cone.

Conformal partial wave expansion of celestial correlators
Journal of High Energy PhysicsA novel definition of holographic correlation functions on the celestial sphere of Minkowski space was recently introduced in [1] as the extrapolation of bulk time-ordered correlation functions to the celestial sphere.

Minkowski space holography and Radon transform
Journal of High Energy PhysicsWe relate a free scalar field in the Minkowski spacetime with a scalar field with a certain scaling dimension on a sphere of codimension two. This is realised by first performing a Radon transform of the “bulk” field on the Minkowski space to a field on ...

PhysicsIn special relativity, particle trajectories, whether mass-bearing or not, can be traced on the Minkowski spacetime manifold in (3+1)D. Meantime, in quantum mechanics, trajectories in the phase space are not strictly outlined because coordinate and ...

Celestial holography revisited. Part II. Correlators and Källén-Lehmann
Journal of High Energy PhysicsIn this work we continue the investigation of the extrapolate dictionary for celestial holography recently proposed in [1], at both the perturbative and non-perturbative level.

Orthogonality in Generalized Minkowski Spaces
, 2016 We combine functional analytic and geometric viewpoints on approximate Birkhoff and isosceles orthogonality in generalized Minkowski spaces which are finite-dimensional vector spaces equipped with a gauge. This is the first approach to orthogonality types in such spaces.

Diffusion on $\kappa$-Minkowski space
, 2014 We study the spectral dimension associated with diffusion processes on Euclidean $\kappa$-Minkowski space. We start by describing a geometric construction of the "Euclidean" momentum group manifold related to $\kappa$-Minkowski space. On such space we identify various candidate Laplacian functions, i.e.
