- By proposition 6.5.4, X is a skeletoid and hence an absorber by theorem 6.5.1.
- 2020, Howard Cook, Continua: With the Houston Problem Book, page 70:
- Skeletoids and absorbers play an important role in infinite-dimensional topology. The existence and uniqueness of skeletoids (and absorbers) with respect to certain collections allow [sic] one to study completely metrizable infinite-dimensional manifolds by using the technique of compact manifolds, incomplete manifolds by those of complete ones and so on.
