X is said to be locally convex (l.c.) if there is a basis of neighborhoods in X consisting of convex sets. Locally convex spaces are by far the most important class of t.v.s. and we will present later on several examples of such t.v.s.. For the moment let us focus on the properties of the ﬁlter of neighbourhoods of locally convex spaces.
