On singular semi-Riemannian manifolds

- O. Stoica
- Mathematics
- 1 May 2011

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… Expand

Beyond the Friedmann-Lemaitre-Robertson-Walker Big Bang singularity

- O. Stoica
- Mathematics
- 8 March 2012

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… Expand

Leptons, Quarks, and Gauge from the Complex Clifford Algebra $$\mathbb {C}\ell _6$$Cℓ6

- O. Stoica
- Mathematics
- 5 May 2018

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… Expand

Revisiting the Black Hole Entropy and the Information Paradox

- O. Stoica
- PhysicsAdvances in High Energy Physics
- 13 July 2018

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… Expand

REAL CONVERGENCE AND EUROPEAN INTEGRATION WITH FOCUS ON THE NEW MEMBER STATES

- O. Stoica, Angela Roman, D. Diaconaşu
- EconomicsScientific Annals of Economics and Business
- 28 December 2019

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… Expand

Representation of the wave function on the three-dimensional space

- O. Stoica
- PhysicsPhysical 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… Expand

Schwarzschild’s singularity is semi-regularizable

- O. Stoica
- Mathematics
- 21 November 2011

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… Expand
