Abstract
In this paper we study quark matter and strange quark matter in higher-dimensional spherical symmetric space-times. We analyze strange quark matter for the different equations of state and obtain the space-time geometry of quark and strange quark matter. We also discuss the features of the obtained solutions in the context of higher-dimensional general theory of relativity.

For the line element (5) the non zero component of \(R_{jij}^{i}\) is
where i=3,4,5,…,n j=2,3,4,…,n−1 and i>j.
Examination of this expression reveals that if R=r our line element (5) reduces to
If curvature coordinates used in empty region then spherically symmetric five dimensions (5D) Schwarzschild’s like metric is given by
where A is a constant and from Newtonian approximation A=M. Comparison of (43) and (44) gives
where the subscript b means evaluation at the boundary. We can, at this stage, follow the arguments of Cahill and McVittie [21] in defining intuitively a mass function in 5D as
