Query: Vacuum polarization by fermionic fields in higher dimensional cosmic
  string space-time   In this paper we investigate vacuum polarization effects associated with
charged massive quantum fermionic fields in a six-dimensional cosmic string
space-times considering the presence of a magnetic flux running along its core.
We have shown that for specific values of the parameters which codify the
presence of the cosmic string, and the fractional part of the ratio of the
magnetic flux by the quantum one, a closed expression for the respective Green
function is obtained. Adopting this result, we explicitly calculate the
renormalized vacuum expectation value of the energy-momentum tensors,
$<T^A_B>_{Ren}$, and analyse this result in some limitting cases.
