On singular semi-Riemannian manifolds
On a Riemannian or a semi-Riemannian manifold, the metric determines invariants like the Levi-Civita connection and the Riemann curvature. If the metric becomes degenerate (as in singular
Beyond the Friedmann-Lemaitre-Robertson-Walker Big Bang singularity
Einstein's equation, in its standard form, breaks down at the Big Bang singularity. A new version, equivalent to Einstein's whenever the latter is defined, but applicable in wider situations, is
Leptons, Quarks, and Gauge from the Complex Clifford Algebra $$\mathbb {C}\ell _6$$Cℓ6
A simple geometric algebra is shown to contain automatically the leptons and quarks of a family of the Standard Model, and the electroweak and color gauge symmetries, without predicting extra
Elasticity of Membrane Vesicles Isolated from Pseudomonas aeruginosa
TLDR
Thickness measurements on dried and hydrated MVs showed that varying amounts of periplasmic molecular components are encapsulated by MVs, and analysis of the spring constants gave MV osmotic pressures on the order of atmospheres suggested that the MV envelope is under tension.

The black hole information paradox and the black hole entropy are currently extensively researched. The consensus about the solution of the information paradox is not yet reached, and it is not yet
REAL CONVERGENCE AND EUROPEAN INTEGRATION WITH FOCUS ON THE NEW MEMBER STATES
Our paper aims to analyse the dynamics of real economic convergence and the impact of several macroeconomic and institutional factors on this process, within the EU countries for the period
Representation of the wave function on the three-dimensional space

    Physical Review A
  • 28 June 2019
One of the major concerns of Schrodinger, Lorentz, Einstein, and many others about the wavefunction is that it is defined on the $3\mathbf{N}$-dimensional configuration space, rather than on the
Schwarzschild’s singularity is semi-regularizable
It is shown that the Schwarzschild spacetime can be extended so that the metric becomes analytic at the singularity. The singularity continues to exist, but it is made degenerate and smooth, and the
