  For a partition $a$ and a vector bundle $E$ on a projective variety $X$ let
$\mathcal{F}l_s(E)$ be the corresponding flag manifold. There is a line bundle
$\it Q_a^s$ on $\mathcal{F}l_s(E)$ with $p:\mathcal{F}l_s(E)\to X $ and $\it
p_*Q_a^s = \mathcal{S}_aE$. We prove, if $\mathcal{S}_aE $ is $k$-ample (in the
sense of Sommese) then $\it Q_a^s$ is $k$-ample. For the inverse if $\it Q_a^s$
is $k$-ample, we prove that one of two the conditions of k-ampleness namely the
cohomological vanishing is proved here but not yet the condition of
semiamplenes of $\mathcal{S}_aE $ .
