It refers to a set S and P(x) be a property that elements of S may or may not satisfy. We may define a new set to be the set of all elements x in S such that P(x) is true. The set is denoted as follows: { x ∈ S|P(x)}
Question
It refers to a set S and P(x) be a property that elements of S may or may not satisfy. We may define a new set to be the set of all elements x in S such that P(x) is true. The set is denoted as follows: { x ∈ S|P(x)}
Solution
The text you provided is a description of a concept in set theory, a branch of mathematical logic that studies sets, which are collections of objects.
The notation { x ∈ S | P(x) } is used to denote a subset of S, consisting of elements x for which the property P(x) holds true.
Here's a step-by-step breakdown:
-
We start with a set S, which contains various elements.
-
P(x) is a certain property or condition. An element x from the set S may or may not satisfy this property.
-
We then define a new set. This set contains all the elements x from the original set S that satisfy the property P(x). In other words, for these elements, P(x) is true.
-
This new set is denoted as { x ∈ S | P(x) }. The vertical bar "|" can be read as "such that". So, the notation { x ∈ S | P(x) } can be read as "the set of all x in S such that P(x) is true".
For example, if S is the set of all integers, and P(x) is the property "x is even", then the set { x ∈ S | P(x) } would be the set of all even integers.

B = {x | x is a prime number}.This is read “B = the set of all x such that x is a prime number,” and it meansthat the elements of B are the values of x that make the statement “x is a primenumber” come out true. You should think of the statement “x is a prime number”as an elementhood test for the set. Any value of x that makes this statementcome out true passes the test and is an element of the set. Anything else failsthe test and is not an element. Of course, in this case the values of x that makethe statement true are precisely the prime numbers, so this definition says thatB is the set whose elements are the prime numbers, exactly as before.Example 1.3.2. Rewrite these set definitions using elementhood tests:1. E = {2, 4, 6, 8, . . .}.
