In this paper, an explicit characterization of the separation properties T0
and T1 at a point p is given in the topological category of proximity spaces.
Furthermore, the (strongly) closed and (strongly) open subobjects of an
object are characterized in the category of proximity spaces and also the
characterization of each of the various notions of the connected objects in
this category are given.
Keywords: topological category, proximity space, separation, closedness, connectedness
