"The Fine Topology" C(X,Y) where (Y,d) is a metric space is
referred to, in an exercise in [14], as the topology generated by basic
open neighborhoods of the form B(f,E) = {g: d(f(x),g(x)) < E(x)} where
E is a positive continuous real valued function. So in the fine
topology, a function g is close to f if g(x) is continuously close to
f(x); whereas in the uniform topology, g(x) must be uniformly close to
f(x), that is, within a constant distance of f(x). So the fine topology
is an obvious refinement of the uniform topology.
This topology has not been extensively studied before, and it is
the purpose of this paper to see how the fine topology fits in with the
lattice of other well studied topologies on C(X,Y), and to study some
properties of this topology in itself. Furthermore, other results on these well studied topologies will-be examined and compared with the
fine topology.
