Antony S. R. Manstead,Gün R. SeminIn this chapter we prove two of the most important results for covering dimension, the countable sum theorem for normal spaces and the subset theorem for perfectly normal spaces. Both results are due to Čech.

https://doi.org/10.1007/978-3-662-09956-8The inequalities in Propositions 4.3, 4.8 and Exercise 4.15 are known as . in honour of Urysohn who proved the inequality for the small inductive dimension of compact metric spaces. The Urysohn inequality for large inductive dimension will be used in the next section to compute the precise value of the inductive dimensions of Euclidean spaces.

Anthony S. R. Manstead,Gün R. SeminConsider the following axioms for a dimension function . on a class of spaces . that contains all Euclidean cubes . and every space that is homeomorphic to a subspace of a member of .. Bear in mind that by our definition of a dimension function, . if . and . are homeomorphic, and . iff . = ∅.
