  The purpose of this paper is to study anti-invariant Riemannian submersions
from Kenmotsu manifolds onto Riemannian manifolds. Several fundamental results
in this respect are proved. The integrability of the distributions and the
geometry of foliations are investigated. We proved that there do not exist
(anti-invariant) Riemannian submersions from Kenmotsu manifolds onto Riemannian
manifolds such that characteristic vector field {\xi} is a vertical vector
field. We gave a method to get horizontally conformal submersion examples from
warped product manifolds onto Riemannian manifolds. Furthermore, we presented
an example of anti-invariant Riemannian submersions in the case where the
characteristic vector field {\xi} is a horizontal vector field and an
anti-invariant horizontally conformal submersion such that {\xi} is a vertical
vector field.
