This is an announcement for the paper "Khinchin's inequality,
Dunford--Pettis and compact operators on the   space $\pmb{C([0,1],X)}$"
by Dumitru Popa.


Abstract: We prove that if $X,Y$ are Banach spaces, $\Omega$ a
compact Hausdorff space and $U\hbox{\rm :}\ C(\Omega,X)\rightarrow
Y$ is a bounded linear operator, and if $U$ is a Dunford--Pettis
operator the range of the representing measure $G(\Sigma) \subseteq
DP(X,Y)$ is an uniformly Dunford--Pettis family of operators and
$\|G\|$ is continuous at $\emptyset$. As applications of this result
we give necessary and/or sufficient conditions that some bounded
linear operators on the space $C([0,1],X)$ with values in $c_{0}$
or $l_{p}$, ($1\leq p<\infty$) be Dunford--Pettis and/or compact
operators, in which, Khinchin's inequality plays an important role.
