Compactness and Its Different Forms: Separation Axioms,A space . is called . if every open cover of . contains a finite subcover. A compact Hausdorff space will be called a .. We shall see that the Hausdorff separation axiom has a great impact on the properties of compact spaces.

Continuous Mappings of Compact Spaces,One of the most fundamental properties of compactness is its invariance under continuous mappings.

Cardinal Invariants in the Class of Compacta,A . is a function defined on the class of all topological spaces or on any of its subclasses whose values are infinite cardinal numbers and has the property that for homeomorphic spaces the function assumes the same value. In general topology the theme of cardinal invariants plays a crucial role. We will provide some reasons why this is the case.

Scaling Laws for Diesel Combustion Systems, the credit for the creation and growth of general topology must be given to the theory of functions. Precisely this theory provided (and is still providing) the enlightenment and energy responsible for the development of modern general topology.

Metrizability Conditions for Compact, Countably Compact and Pseudocompact Spaces,riety of very diverse metrizability theorems related to compact spaces. It is possible to consider the question of metrizability of compact spaces as a small part of the theory of cardinal invariants of such spaces (see the following section). This part, however, is so special and important that it deserves a separate treatment.

Axonal Navigation Through Voxel Substratess appeared in mathematics for the first time as one of the main topological properties of an interval, a square, a sphere and any closed, bounded subset of a finite dimensional Euclidean space. Once it was realized that precisely this property was responsible for a series of fundamental facts relate
