More precisely, for each pair of integers n,k > 0, let M(n,k) be the set of real n×k matrices. Let Cn,k be the set of all uniformly bounded, uniformly continuous functions from R to M(n,k), equipped with the topology of uniform convergence on compact sets (compact-open topology).

In the theory of retarded functional differential equations with unbounded delay frequently we need additional properties of the space to obtain some results. Next we denote by the space of continuous functions from into X with compact support. It is clear from the axioms of phase space that . In this work we consider the following axiom [14]. If a uniformly bounded sequence in converges to a function ϕ in the compact-open topology, then ϕ belongs to and , as .
