Deferred Cesàro conull FK spaces
In this paper, we study the (strongly) deferred Cesàro conull FK-spaces and we give some characterizations. We also apply these results to summability domains.

Some Subspaces of an FK Space and Deferred Cesàro Conullity
In this paper, we construct new important the subspaces $D_{p}^{q}S$, $D_{p}^{q}W$, $D_{p}^{q}F$ and $D_{p}^{q}B$ for a locally convex FK-space $X$ containing $ϕ$, the space of finite sequences. Then we show that there is relation among these subspaces. Also, we study deferred Cesàro conullity of one FK-space with respect to another, and we give some important results. Finally, we examine the deferred Cesàro conullity of the absolute summability domain $l_A$, and show that if $l_A$ is deferred Cesàro conull, then $A$ cannot be $l$-replaceable.
