Schauder basis in a locally k-convex space and perfect sequence spaces

R. Ameziane, Abdelkhalek El Amrani, Mohammed Babahmed


In this work, we are dealing with the natural topology in a perfect sequence space and the transfert of topologies of a locally K — convex space E with a Schauder basis (ei )i to such Space. We are also interested with the compatible topologies on E for which the basis(ei )i is equicontinuous, and the weak basis problem. Finally, we give some applications to barrelled Spaces and G—Spaces.
