Fractal dimension of the cosmic web with different galaxy types
Ana Elisa Lima, Julianne C. Soares, Ana Carolina S. Tavares +4
The fractal dimension is used to map the large-scale galaxy distribution in the Universe by color types: blue, green and red. Using a -complete COSMOS2020 subsample of 6…
World personal income distribution evolution measured by purchasing power parity exchange rates
J. D. A. Islas-García, M. del Castillo-Mussot, Marcelo B. Ribeiro
The evolution of global income distribution from 1988 to 2018 is analyzed using purchasing power parity exchange rates and well-established statistical distributions. This research…
Modeling Income Distribution with the Gause-Witt Population Ecology System
Marcelo B. Ribeiro
This paper presents an empirical application of the Gause-Witt model of population ecology and ecosystems to the income distribution competitive dynamics of social classes in econo…
Galaxy Distributions as Fractal Systems
Sharon Teles, Amanda R. Lopes, Marcelo B. Ribeiro
This paper discusses if large scale galaxy distribution samples containing almost one million objects can be characterized as fractal systems. The analysis performed by Teles et al…
Warp drive dynamic solutions considering different fluid sources
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
Alcubierre proposed in 1994 that the well known special relativistic limitation that particles cannot travel with velocities bigger than the light speed can be bypassed when such t…
Perfect fluid warp drive solutions with the cosmological constant
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
The Alcubierre metric describes a spacetime geometry that allows a massive particle inside a spacetime distortion, called warp bubble, to travel with superluminal global velocities…
