Sharp estimates for the Laplacian torsional rigidity with negative Robin boundary conditions
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract Motivated by pioneering works of Bandle and Wagner, given a bounded Lipschitz domain Ω⊂Rd$\Omega \subset \mathbb {R}^d$ with d⩾3$d\geqslant 3$, we consider the Robin–Laplacian torsional rigidity τα(Ω)$\tau _\alpha (\Omega)$ with negative boundary parameter α$\alpha$ and we show that sharp inequalities for τα(Ω)$\tau _\alpha (\Omega)$ hold if ...

Space and time: Minkowski's papers on relativity
, 2012 This is the first publication (in German or English) of Hermann Minkowski's three papers on relativity together: (i) The Relativity Principle - lecture given at the meeting of the Göttingen Mathematical Society on November 5, 1907 (the first English ...

Spline Split Quaternion Interpolation in Minkowski Space
, 2013 Spherical spline quaternion interpolation has been done on sphere in Euclidean space using quaternions. In this paper, we have done the spline split quaternion interpolation on hyperbolic sphere in Minkowski space using split quaternions and metric ...

Thurston norm for coherent right‐angled Artin groups via L2$L^2$‐invariants
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract We define a new notion of splitting complexity for a group G$G$ along a non‐trivial integral character ϕ∈H1(G;Z)$\phi \in H^1(G; \mathbb {Z})$. If G$G$ is a one‐ended coherent right‐angled Artin group, we show that the splitting complexity along an epimorphism ϕ:G→Z$\phi \colon G \rightarrow \mathbb {Z}$ equals the L2$L^2$‐Euler characteristic

Global properties of codimension two spacelike submanifolds in Minkowski space [PDF]
, 2010 We consider codimension two spacelike submanifolds with a parallel normal field (i.e. vanishing normal curvature) in Minkowski space. We use the analysis of their contacts with hyperplanes and hyperquadrics in order to get some global information on them.

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

ON SPACE-LIKE GENERALIZED CONSTANT RATIO HYPERSUFACES IN MINKOWSKI SPACES
, 2022 In this work, we move the study of generalized constant ratio hypersurfaces started in [6] into the Minkowski space. First, we get some geometrical properties of a non-degenerated GCR hypersurface in an arbitrary dimensional Minkowski space.

Geometry of Minkowski Space-Time
, 2011 This book provides an original introduction to the geometry of Minkowski space-time. A hundred years after the space-time formulation of special relativity by Hermann Minkowski, it is shown that the kinematical consequences of special relativity are ...

Cubic helices in Minkowski space
, 2006 We discuss space-like and light-like polynomial cubic curves in Minkowski (or pseudo-Euclidean) space R 2;1 with the property that the Minkowski-length of the first derivative vector (or hodograph) is the square of a polynomial.
