Summary: [For the entire collection see Zbl 0723.00046.]
We study some geometrical questions related to partial realization. In particular, we construct a cellular decomposition of the space S(n,\(\tau\)) of all finite sequences of fixed length \(\tau\) which have a minimal realization of dimension \(n\leq \tau\). Moreover, we present continuity results for different canonical realization maps on the sequence spaces S(n,\(\tau\)).
