Wolfgang Stroebe,Klaus Jonas,Miles Hewstoneiven ., 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.

Zum Gegenstand der Sozialpsychologie and published in full detail in Roy (Trans Am Math Soc 134:117–132, 1968), is generally considered to be of forbidding complexity. In this chapter we present Kulesza’s much simpler metrizable space . with . and ., published in his paper Kulesza (Topol Appl 35:109–120, 1990) of 1990.

Book 2019e emphasis on the negative results for more general spaces, presenting a readable account of numerous counterexamples to well-known conjectures that have not been discussed in existing books. Moreover, it includes three new general methods for constructing spaces: Mrowka‘s psi-spaces, van Douwen‘s t
