Set theory, the mathematical study of collections of objects, forms a foundation for much of modern mathematics, while cardinal functions provide a means to quantify the sizes of these sets, ...

Set theory is a mathematical abstract concerned with the grouping of sets of numbers that have commonality. For example, all even numbers make up a set, and all odd numbers comprise a set. All numbers ...

Proceedings of the American Mathematical Society, Vol. 106, No. 3 (Jul., 1989), pp. 821-828 (8 pages) This paper concerns applications of set theory to the problem of calculating the strong homology ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...

Systems theory was not originally a business theory. Indeed, systems theory was proposed in the 1940s by biologist Ludwig von Bertalanffy, say Francis Heylighen and Cliff Joslyn in their article, ...
