J of open subsets of the real line is called an ω-cover of a set X iff every finite subset of X is contained in an element of J. A set of reals X is a γ-set iff for every ω-cover J of X there exists 〈Dn: n < ω〉ϵJω such that ...
Most of us believe we have a reasonable understanding of what a real number is. However, sets of real numbers have some deep and surprising properties. We will explore some of these properties in this chapter and in Chap. 4 on cardinality. Of notable int

Sets are defined as a collection of distinct elements. The elements of a set share a common characteristic among them. Learn about sets definition, representation, types, symbols, formulas, and their properties with some solved examples.

Sets are clusters of numbers that can be acted upon through interesting operations. There are multiple types of sets, and the union of sets is one of the possible multiple operations. It refers to the collection of all the elements in individual subsets. The union of sets has distinguishing ...
In Number Theory the universal set is all the integers, as Number Theory is simply the study of integers. But in Calculus (also known as real analysis), the universal set is almost always the real numbers. And in complex analysis, you guessed it, the universal set is the complex numbers...
Find out the intersection of the following sets: A = {set of natural numbers}, B = {set of whole numbers}. Draw the Venn Diagram of intersection between A = {0, 3, 5, 7, 9, 10} and B = {2, 4, 6}. Explain whether the sets above are disjoint sets or intersecting sets. Give...
