On Isoperimetric Inequalities in Minkowski Spaces [PDF]
Journal of Inequalities and Applications, 2010 This paper gives a collection of isoperimetric-type inequalities involving convex bodies, their intersection and projection bodies, polars and Steiner symmetrals, and states some conjectures and open questions. It is shown how some of these inequalities are related to classic isoperimetric problems in Minkowski geometry.

Vacuum thermal effects in flat space-time from conformal quantum mechanics
Journal of High Energy Physics, 2021 The generators of radial conformal symmetries in Minkowski space-time can be mapped to the generators of time evolution in conformal quantum mechanics.

Fuchsian convex bodies: basics of Brunn--Minkowski theory
, 2012 The hyperbolic space $ \H^d$ can be defined as a pseudo-sphere in the $(d+1)$ Minkowski space-time. In this paper, a Fuchsian group $\Gamma$ is a group of linear isometries of the Minkowski space such that $\H^d/\Gamma$ is a compact manifold.

Stability of Minkowski Space-Time with a Translation Space-Like Killing Field [PDF]
, 2015 In this paper we prove the nonlinear stability of Minkowski space-time with a translation Killing field. In the presence of such a symmetry, the $$3+1$$3+1 vacuum Einstein equations reduce to the $$2+1$$2+1 Einstein equations with a scalar field. We work

Higher-Rank Fields and Currents
, 2016 $Sp(2M)$ invariant field equations in the space ${\cal M}_M$ with symmetric matrix coordinates are classified. Analogous results are obtained for Minkowski-like subspaces of ${\cal M}_M$ which include usual $4d$ Minkowski space as a particular case.

Realizations of $$\kappa $$κ-Minkowski space, Drinfeld twists, and related symmetry algebras [PDF]
, 2015 Realizations of $$\kappa $$κ-Minkowski space linear in momenta are studied for time-, space- and light-like deformations. We construct and classify all such linear realizations and express them in terms of the $$\mathfrak {gl}(n)$$gl(n) generators. There

Deformed Special Relativity and Deformed Symmetries in a Canonical Framework
, 2007 In this paper we have studied the nature of kinematical and dynamical laws in $\kappa $-Minkowski spacetime from a new perspective: the canonical phase space approach. We discuss a particular form of $\kappa$-Minkowski phase space algebra that yields the

Celestial holography and AdS 3/CFT 2 from a scaling reduction of twistor space
Journal of High Energy Physics, 2023 Celestial amplitudes obtained from Mellin transforming 4d momentum space scattering amplitudes contain distributional delta functions, hindering the application of conventional CFT techniques.

Cauchy Horizons, Thermodynamics and Closed Time-like Curves in Planar Supersymmetric Space-times
, 1992 We study geodesically complete, singularity free space-times induced by supersymmetric planar domain walls interpolating between Minkowski and anti-de Sitter ($AdS_4$) vacua.

Comparison of particle properties in Kerr metric and in rotating coordinates [PDF]
, 2017 Properties of particles in Kerr metric are compared with properties of particles in rotating coordinates in Minkowski space-time. It is shown that particles with negative and zero energies existing in the ergosphere of the rotating black hole also exist ...
