Collapsing and Expanding Cylindrically Symmetric Fields with Ligh-tlike Wave-Fronts in General Relativity
Paulo R. C. T. Pereira, A. Z. Wang
The dynamics of collapsing and expanding cylindrically symmetric gravitational and matter fields with lightlike wave-fronts is studied in General Relativity, using the Barrabes-Isr…

Dynamics of Rotating Cylindrical Shells in General Relativity
P. R. C. T. Pereira, Anzhong Wang
Cylindrical spacetimes with rotation are studied using the Newmann-Penrose formulas. By studying null geodesic deviations the physical meaning of each component of the Riemann tens…

Gravitational Collapse of Cylindrical Shells Made of Counter-Rotating Dust Particles
P. R. C. T. Pereira, Anzhong Wang
The general formulas of a non-rotating dynamic thin shell that connects two arbitrary cylindrical regions are given using Israel's method. As an application of them, the dynamics o…
