,-Spaces and the Failure of the Sum and Subset Theorems for ,,,iven ., we present a Tychonoff space . which is the union of two zero subspaces .., .. such that dim... = dim... = 0 while dim.. = .. We also construct Tychonoff spaces . with dim.. = 0 that contain zero subspaces . with dim.. as large as we wish, showing the failure of the subset theorem for dim. in a strong form.

Antony S. R. Manstead,Gün R. Seminnly defining the meaning of the statement d(.) ≤ . for every non-negative integer . and every space .. It will then be understood that (1) d(.) ≤−1 iff . = ∅, (2) d(.) = . if the statement d(.) ≤ . is false for every integer . ≥−1 and (3) if d(.) ≤ . is true for some integer . ≥−1, then d(.) is the first such integer.

Wolfgang Stroebe,Klaus Jonas,Miles Hewstoneng a normal subspace .. with .. This shows that the subset theorem for the covering or large inductive dimension of normal Hausdorff spaces does not always hold. The two examples together show that on the class of normal Hausdorff spaces, ., . and . are distinct dimension functions and the only relations between them are . and ..

Book 2019standard facts of general topology, the book is written in a reader-friendly style suitable for self-study. It contains enough material for one or more graduate courses in dimension theory and/or general topology. More than half of the contents do not appear in existing books, making it also a good reference for libraries and researchers..
