Abstract

The concept of a normed quasilinear space was dened by Aseev in [1]. Based on this concept, topological quasilinear spaces are given in [5] and their properties are analysed. Denition of seminormed quasilinear spaces based on these denitions was given in [8] and their topological structure is analysed in this reference. In this paper we will introduce paranormed and locally convex quasilinear spaces and will give some examples. We observe that every normed quasilinear space is a paranormed quasilinear space. Finall we will prove that the topology of a locally convex quasilinear space comes from a family of seminorms which are dened on the quasilinear space.
