A linear representation $ \rho $
in an invariant subspace $ F \subset E $
of a representation $ \pi $
of a group (algebra, ring or semi-group) $ X $
in a (topological) vector space $ E $
defined by the formula $ \rho ( x) \xi = \pi ( x) \xi $
for all $ \xi \in F $,
$ x \in X $.
If $ \pi $
is a continuous representation (of a topological group, algebra, ring, or semi-group), then any subrepresentation of it is also continuous.
