CHAP03 Sets, Functions and Relations
... §3.7. The Sum and Product of Relations If R and S are relations on the set X then the sum of R and S is the relation R + S defined on X by: x(R+S)y if xRy or xSy. As sets, this is simply the union: S + T = S ∪ T. Example 10: The relation “spouse of” means “husband or wife of”. If H = “husband of” an ...

Infinity
Infinity (symbol: ∞) is an abstract concept describing something without any limit and is relevant in a number of fields, predominantly mathematics and physics.In mathematics, ""infinity"" is often treated as if it were a number (i.e., it counts or measures things: ""an infinite number of terms"") but it is not the same sort of number as natural or real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number; see 1/∞.Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.
