What in the World Are 4D Shapes?

open access: yesNoûs, EarlyView.
ABSTRACT It is often said that in special relativity, 4D shapes can be used to explain 3D shape projections onto frames of reference. Perdurantists have frequently used this as a motivation for their view of persistence. Despite this, philosophers never clearly state what 4D shapes are.

Time-like loxodromes on helicoidal surfaces in Minkowski 3-space

open access: yes, 2017
Loxodromes in Euclidean 3-space are often used in navigation. We study time-like loxodromes which cut all meridians on helicoidal surfaces at a constant Lorentzian angle in Minkowski 3-space.

Timelike surfaces with Bertrand geodesic curves in Minkowski 3–space

open access: yesAIP Advances
Geodesic curves on a surface play an essential role in reasonable implementation. A curve on a surface is a geodesic curve if its principal normal vector is aligned with the surface normal. Using the Serret–Frenet frame, the timelike (TL) surfaces can be

On Null Cartan Normal Helices in Minkowski 3-Space

open access: yesAxioms
In this paper, we introduce null Cartan normal helices in Minkowski space E13. We obtain explicit expressions for their torsions by considering the cases when the C-constant vector field is orthogonal to their axis or not orthogonal to it.

A New Take on Sharp Cracks in Brittle Dielectrics: Where Electric Dipole Layers Meet Concentrated Line Forces

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT In this work, novel electrostatic aspects of sharp cracks in brittle dielectrics are discussed using the example of an impermeable Griffith crack in an infinite linear isotropic dielectric plate. On the one hand, electrostatic force densities stemming from the Maxwell stress tensor according to Lorentz are derived mathematically, where the ...

Flexible polyhedra in the Minkowski 3-space [PDF]

open access: yes, 2001
We prove that flexible polyhedra do exist in the Minkowski 3-space and each of them preserves the (generalized) volume and the (total) mean curvature during a flex.

Frenet frames and invariants of timelike ruled surfaces

open access: yesAin Shams Engineering Journal, 2013
In this study we give the Frenet frames and Frenet invariants of timelike ruled surfaces. We show that a timelike ruled surface and its directing cone have the same base of Frenet frame.

Insights Into Electrolyte Effects on Interfacial Kinetics and Transport in Porous Redox Flow Battery Electrodes: A Multiparadigm Modeling Study

open access: yesBatteries &Supercaps, Volume 9, Issue 11, November 2026.
A multiparadigm modeling framework coupling kinetic Monte Carlo and lattice Boltzmann simulations is developed to investigate the combined effects of electrolyte composition and porous electrode microstructure in redox flow batteries. The approach links interfacial electrochemical kinetics with pore‐scale transport, revealing coupled transport–reaction

Characterization of k,m-Type Slant Helices Using the Modified Orthogonal Frame in Minkowski 3-Space

open access: yesJournal of Mathematics
Within the scope of differential geometry, exploring how curves relate to each other has long been a broad area of study for many scholars. When investigating curves, particularly space curves, the concept of frame fields, such as the Frenet–Serret frame,
