Linear Nash-Greene fluctuations on the evolution of and tensions
Abraão J. S. Capistrano, Luís A. Cabral, José A. P. F. Marão +1
We present the perturbation equations in an embedded four space-time from the linear Nash-Greene fluctuations of background metric. In the context of a five-dimensional bulk, we sh…
Acceleration of charged particles from near-extremal rotating black holes embedded in magnetic fields
C. H. Coimbra-Araújo, R. C. Anjos
The aim of the present article is to evaluate the motion of charged test particles in the vicinity of a near-extremal rotating black hole in the presence of magnetic fields. Euler-…
COVID-19: A model for studying the evolution of contamination in Brazil
Rodrigo A. Schulz, Carlos H. Coimbra-Araújo, Samuel W. S. Costiche
In the present article we introduce an epidemiological model for the investigation of the spread of epidemics caused by viruses. The model is applied specifically to COVID-19, the…
Ultra high energy cosmic rays and possible signature of black strings
Rita C. Anjos, Carlos H. Coimbra-Araújo, Roldao da Rocha +1
Ultra high energy cosmic rays (UHECRs) probably originate in extreme conditions in which extra dimension effects might be important. In this paper we calculate the correction in bl…
