Theory of Relativity [PDF]

open access: yesPhysics Bulletin, 1959
By W. Pauli. London: Pergamon Press Limited. Pp. xiv + 241. Price 35s. It is evidence of Pauli's genius that this book written thirty-eight years ago, when the author was only twentyone, should now be published in an English edition. It remains in its original form in order, we are told, "to preserve the character of the book as an historical document."

Shape Dynamics [PDF]

open access: yes, 2013
Barbour's formulation of Mach's principle requires a theory of gravity to implement local relativity of clocks, local relativity of rods and spatial covariance. It turns out that relativity of clocks and rods are mutually exclusive.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Basic statements of relativity theory

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2010
Some basic statements of relativity theory, starting out with geometry and observers up to Einstein's field equations, are collected in a systematical order without any proof, to serve as a short survey of tools and results.

The jump and stagnation of mass with speed

open access: yesIET Quantum Communication, 2022
In the general theory of relativity, the four‐dimensional space‐time of describing a mass body accelerated motion or in a gravitational field, although it is a curved Riemannian geometric space from the perspective of “integral geometry”, but for any ...

Relative index theory

open access: yesJournal of Functional Analysis, 1992
The author studies pairs of generalized Dirac operators on complete noncompact Riemannian manifolds which agree outside compact sets. By an analytic interpretation of the difference of the integrals over their local index densities, he obtains a generalization of the relative index theorem of \textit{M. Gromov} and \textit{H. B. Lawson} jun.

A Glimpse of Special Theory of Relativity [PDF]

open access: yes, 2017
This article provides a brief outline of Special Theory of Relativity. The physics before the relativity, the special relativity in itself, and the consequences of special relativity are discussed ...

Energy and Momentum densities of cosmological models, with equation of state $\rho=\mu$, in general relativity and teleparallel gravity

open access: yes, 2006
We calculated the energy and momentum densities of stiff fluid solutions, using Einstein, Bergmann-Thomson and Landau-Lifshitz energy-momentum complexes, in both general relativity and teleparallel gravity.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Non-linear extension of non-metricity scalar for MOND

open access: yesPhysics Letters B, 2020
General Relativity enjoys the freedom of different geometrical interpretations in terms of curvature, torsion or non-metricity. Within this geometrical trinity, a simpler geometrical formulation of General Relativity manifests itself in the latter, where
