Minkowski functionals of Abell/ACO clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 We determine the Minkowski functionals for a sample of Abell/ACO clusters, 401 with measured and 16 with estimated redshifts. The four Minkowski functionals (including the void probability function and the mean genus) deliver a global description of the spatial distribution of clusters on scales from $10$ to $60\hMpc$ with a clear geometric ...

Quark Mass Function from an OGE-type Interaction in Minkowski Space [PDF]
, 2021 We present results for the quark mass function in Minkowski space calculated from an interaction kernel that consists of an effective one-gluon-exchange and a constant interaction.

The equivariant minkowski problem in minkowski space [PDF]
, 2017 The classical Minkowski problem in Minkowski space asks, for a positive function $\phi$ on $\mathbb{H}^d$, for a convex set $K$ in Minkowski space with $C^2$ space-like boundary $S$, such that $\phi(\eta)^{-1}$ is the Gauss--Kronecker curvature at the ...

Path length distribution in two-dimensional causal sets
European Physical Journal C: Particles and Fields, 2018 We study the distribution of maximal-chain lengths between two elements of a causal set and its relationship with the embeddability of the causal set in a region of flat spacetime.

Minkowski Functionals in Cosmology
Proceedings of the International School of Physics “Enrico Fermi”, 1995 Minkowski functionals provide a novel tool to characterize the large-scale galaxy distribution in the Universe. Here we give a brief tutorial on the basic features of these morphological measures and indicate their practical application for simulation data and galaxy redshift catalogues as examples.

Orthogonal polynomials for Minkowski’s question mark function [PDF]
Journal of Computational and Applied Mathematics, 2015 Hermann Minkowski introduced a function in 1904 which maps quadratic irrational numbers to rational numbers and this function is now known as Minkowski's question mark function since Minkowski used the notation $?(x)$. This function is a distribution function on $[0,1]$ which defines a singular continuous measure with support $[0,1]$.

Quantum Theory of Massless Particles in Stationary Axially Symmetric Spacetimes
Entropy, 2021 Quantum equations for massless particles of any spin are considered in stationary uncharged axially symmetric spacetimes. It is demonstrated that up to a normalization function, the angular wave function does not depend on the metric and practically is ...
