How to excite the internal modes of sine-Gordon solitons
J. A. Gonzalez, A. Bellorin, L. E. Guerrero
We investigate the dynamics of the sine-Gordon solitons perturbed by spatiotemporal external forces. We prove the existence of internal (shape) modes of sine-Gordon solitons when t…
The Weyl tensor and equilibrium configurations of self-gravitating fluids
L. Herrera
It is shown that (except for two well defined cases), the necessary and sufficient condition for any spherically symmetric distribution of fluid to leave the state of equilibrium (…
On Normal Stratified Pseudomanifolds
G. Padilla
A stratified pseudomanifold is normal if its links are connected. A normalization of a stratified pseudomanifold is a normal stratified pseudomanifold together with a finit…
Anisotropic geodesic fluid spheres in general relativity
L. Herrera, J. Martin, J. Ospino
It is shown that unlike the perfect fluid case, anisotropic fluids (principal stresses unequal) may be geodesic, without this implying the vanishing of (spatial) pressure gradients…
The space of signed points and the Self Dual Model
Lorenzo Leal
We study a generalization of the group of loops based on sets of signed points, instead of paths or loops. This geometrical setting incorporates the kinematical constraints of the…
Rotating cylindrical shell source for Lewis spacetime
M. F. A. da Silva, L. Herrera, N. O. Santos +1
Rotating thin-shell-like sources for the stationary cylindrically symmetric vacuum solutions (Lewis) are constructed and studied. It is found, by imposing the non existence of time…
