Normal systems over ANR’s, rigid embeddings and nonseparable absorbing sets
Normal systems over ANR’s, rigid embeddings and nonseparable absorbing sets
Most of results of Bestvina and Mogilski [Characterizing certain incomplete infinite-dimensional absolute retracts. Michigan Math. J., 33, 291–313 (1986)] on strong Z-sets in ANR’s and absorbing sets is generalized to nonseparable case. It is shown that if an ANR X is locally homotopy dense embeddable in infinite-dimensional Hilbert manifolds and …
