We formulate the problem of reconstructing the shape and radiance of a scene as the minimization of the information divergence between blurred images, and propose an algorithm that is provably convergent and guarantees that the solution is admissible, in the sense of corresponding to a positive radiance and imaging kernel. The motivation for the use of information divergence comes from the work...

The following document is to answer if higher dimensions add value to answering fundamental cosmology questions. The results are mixed, 1st with higher dimensions apparently helping in reconstructing and preserving the value of Planck’s constant, and the fine structure constant from a prior to a present universe, while 2nd failing to add anything different from four dimensional cosmological mod...

We describe the deformed Poincare-conformal symmetries implying the covariance of the noncommutative space obeying Snyder’s algebra. Relativistic particle models invariant under these deformed symmetries are presented. A gauge (reparametrisation) independent derivation of Snyder’s algebra from such models is given. The algebraic transformations relating the deformed symmetries with the usual (u...

The noncommutative spacetimes associated to the κ-Poincaré relativistic symmetries and their “non-relativistic” (Galilei) “ultra-relativistic” (Carroll) limits are indistinguishable, since coordinates satisfy same algebra. In this work, we show that three quantum kinematical models can be differentiated when looking at spaces of time-like worldlines. Specifically, construct geodesics with κ-Gal...

In 2019, Denmark declared its military offensive cyber capability operational. This article analyses how this capacity compares to another recent acquisition, the F-35 multirole combat aircraft, in Denmark’s general security strategy. Snyder’s article, “The Security Dilemma Alliance Politics”, from 1984 explain why and strategic challenge for Danish decision-makers is minimize risk of abandonme...
