Topological subcategories of Action V G #
For a concrete category V, where the forgetful functor factors via TopCat,
and a monoid G, equipped with a topological space instance,
we define the full subcategory ContAction V G of all objects of Action V G
where the induced action is continuous.
We also define a category DiscreteContAction V G as the full subcategory of ContAction V G,
where the underlying topological space is discrete.
Finally we define inclusion functors into Action V G and TopCat in terms
of HasForget₂ instances.
