چكيده فارسي :
A space-time can be regarded as a partially ordered set by
causal relations. Space-times which can be continuously represented by
spheres in Euclidean space are rare. There are various definitions for dimension
of a poset. In this paper, it is shown that the definition of dimension
sphere ordering is equivalent to the definition of dimension Euclidian and
by an example is given a technique to find the space-times that can not
admit a sphere order representation
