It is proved that the Cesàro space $\operatorname{Ces}_{p}[0,1]$, $1\le p\infty$, contains a complemented subspace isomorphic to $l^q$ if and only if either $q=1$ or $q=p$. A class of subspaces of this space that contain complemented copies of the space $l^p$ is distinguished. Bibliography: 16 titles.
Keywords: Banach lattices, Cesàro spaces, complemented subspaces, copies of $l^q$-spaces, sublinear operators.
