Categorical Interpretations of Absolutes and Extensions,, namely extensions. (To a much lesser extent we have studied covers in the same way.) Thus, in Chapter 5, we showed that the Stone-Čech compactification, the maximum zero-dimensional compactification, and the Hewitt realcompactification are all specific examples of the same phenomenon.

Lattices, Filters, and Topological Spaces,n the middle of the chapter, we introduce spaces whose topologies are defined by an order, and prove that such spaces are hereditarily normal. The chapter closes with a summary of the properties of well-ordered sets and ordinal numbers, and an investigation of the order topology on an ordinal number.

Extremally Disconnected Spaces and Absolutes,(f,g) and in the study of extension properties (see 5.9(c)). Roughly speaking, if you cannot construct a homeomorphism between X and Y, constructing a perfect continuous surjection between them is the next best goal.

actifications, realcompactifications, H-elosed extension- has long been a major area of study in general topology. A ubiquitous method of constructing an extension of a space is to let the "new points" of the extension be ultrafilters on certain lattices associated with the space. Examples of such l
