The relativistic time evolution of multi-layer spherically symmetric shell systems—consisting of infinitely thin shells separated by vacuum regions—is examined. Whenever two shells collide the evolution is continued with the assumption that the collision is totally transparent. The time evolution of various multi-layer shell systems—comprising large number of shells thereby mimicking the behavior of a thick shell making it possible to study the formation of acoustic singularities—is analyzed…

Repeated crossing of two concentric spherical thin-shells with charge
Interaction / collision of two concentric spherical thin-shells of linear fluid resulting in collapse has been considered recently. We show that addition of finely tuned electric charges on the

We introduce the locally inertial Godunov method with dynamical time dilation, and use it to give a definitive numerical simulation of a point of shock wave interaction in general relativity starting

Dynamics of General Relativistic Spherically Symmetric Dust Thick Shells
We consider a spherical thick shell immersed in two different spherically symmetric space-times. Using the fact that the boundaries of the thick shell with two embedding space-times must be
Crossing of Spherical Massive Shells in Vacuum Space-Time
We investigate collisions between two spherical massive shells in vacuum space-time by assuming that the shells are transparent. We give an expression for the energy transfer and the change in the
Relativistic dynamics of spherical timelike shells
The dynamics of general relativistic timelike spherically symmetric thin shells of matter is considered, putting special emphasis on the physical interpretation of the models and, therefore, on the
Hamiltonian treatment of the gravitational collapse of thin shells
A Hamiltonian treatment of the gravitational collapse of thin shells is presented. The direct integration of the canonical constraints reproduces the standard shell dynamics for a number of known

The authors analyse the dynamics of the collision of two spherical massive shells in a generally spherically symmetric background, obtaining an expression from the conservation law that imposes a
Evolution of Spherical Shells in General Relativity
We discuss the evolution of thin spherical shells within General Relativity. We start directly from the Einstein equations coupled to an arbitrary spherical matter distribution, and show that the

We construct an idealized spherically symmetric relativistic model of an exploding object within the framework of the theory of surface layers in GR. A Vaidya solution for a radially radiating star

The variational principle for a thin dust shell in General Relativity is constructed. The principle is compatible with the boundary-value problem of the corresponding Euler–Lagrange equations, and

A new numerical framework, based on the use of a simple first-order strongly hyperbolic evolution equations, is introduced and tested in the case of four-dimensional spherically symmetric gravitating
Relativistic shells: Dynamics, horizons, and shell crossing
We consider the dynamics of timelike spherical thin matter shells in vacuum. A general formalism for thin shells matching two arbitrary spherical spacetimes is derived and subsequently specialized to
