Collapsing Scalar Field with Kinematic Self-Similarity of the Second Kind in 2+1 Gravity
R. Chan, M. F. A. da Silva, J. F. Villas da Rocha +1
All the 2+1-dimensional circularly symmetric solutions with kinematic self-similarity of the second kind to the Einstein-massless-scalar field equations are found and their local a…
Fine Structure Constants in n-dimensional Physical Spaces through Dimensional Analysis
Fabricio Casarejos, Jaime F. Villas da Rocha, Roberto Moreira Xavier
We use Vaschy-Buckhingham Theorem as a systematic tool to build univocal n-dimensional extensions of the electric and gravitational fine structure constants and show that their rat…
Type II Fluid Solutions to Einstein Field Equations in N-Dimensional Spherical Spacetimes
Jaime F. Villas da Rocha
A large class of Type II fluid solutions to Einstein field equations in N-dimensional spherical spacetimes is found, wich includes most of the known solutions. A family of the gene…
Gravitational Collapse of Perfect Fluid in N-Dimensional Spherically Symmetric Spacetimes
Jaime F. Villas da Rocha, Anzhong Wang
The Riemann, Ricci and Einstein tensors for N-dimensional spherically symmetric spacetimes in various systems of coordinates are studied, and the general metric for conformally fla…
