A solution for non-stationary, slowly-rotating, cylindrically symmetric, perfect fluid universe
Ruhuna Journal of Science, 2007 An analytic solution for the relativistic field equations is obtained for a non-stationary, slowly rotating, cylindrically symmetric distribution of perfect fluid universe. The new metric, is regular with the exception at the point r = 0.

Higher-dimensional inhomogeneous perfect fluid collapse in f(R) gravity
European Physical Journal C: Particles and Fields, 2017 This paper is about the $$n+2$$ n + 2 -dimensional gravitational contraction of an inhomogeneous fluid without heat flux in the framework of a f(R) metric theory of gravity.

MASS OF PERFECT FLUID BLACK SHELLS [PDF]
Modern Physics Letters A, 1998 The spherically symmetric singular perfect fluid shells are considered when their radii are equal to the event horizon (the black shells). We study their observable masses, depending at least on the three parameters, viz. the square speed of sound in the shell, instantaneous radial velocity of the shell at a moment when it reaches the horizon, and ...

On the Existence of Markov Perfect Equilibria in Perfect Information Games [PDF]
We study the existence of pure strategy Markov perfect equilibria in two-person perfect information games. There is a state space X and each period player's possible actions are a subset of X.

Exact relativistic static charged perfect fluid disks
, 2015 Using the well-known "displace, cut and reflect" method used to generate disks from given solutions of Einstein field equations, we construct static charged disks made of perfect fluid based on the Reissner-Nordstrom solution in isotropic coordinates. We
