A CLASS OF CYLINDRICALLY SYMMETRICAL MODELS WITH HEAT FLOW

摘要: Abstract A cylindrically symmetric metric with two degrees of freedom is considered in connection Einstein's field equations corresponding to a perfect fluid distribution heat flow. class cosmological models flux derived. The have non-zero expansion, shear and acceleration. non-geodetic nature the stream lines are intimately related inhomogeneity. An explicit expression for temperature also obtained. homogeneous stiff-fluid model derived as particular case. All our big bang singularity at t = 0 which all physical kinematical parameters diverge.
