Which of the following is an axiom of Zermelo-Fraenkel Set Theory?
-
The Axiom of Extensionality
-
The Axiom of Pairing
-
The Axiom of Union
-
The Axiom of Choice
The Axiom of Extensionality, the Axiom of Pairing, the Axiom of Union, and the Axiom of Choice are all axioms of Zermelo-Fraenkel Set Theory, which is a widely accepted foundation for modern mathematics.
What is the Axiom of Extensionality?
-
Two sets are equal if and only if they have the same elements.
-
A set can be defined by its properties.
-
The union of two sets is the set of all elements that are in either set.
-
Every set has a unique complement.
The Axiom of Extensionality states that two sets are equal if and only if they have the same elements. This means that the order of the elements in a set does not matter, and that sets with the same elements are considered to be the same set.
What is the Axiom of Pairing?
-
Two sets can be paired to form a new set.
-
A set can be defined by its properties.
-
The union of two sets is the set of all elements that are in either set.
-
Every set has a unique complement.
The Axiom of Pairing states that two sets can be paired to form a new set. This means that given two sets A and B, there exists a set C that contains all the ordered pairs (a, b) where a is an element of A and b is an element of B.
What is the Axiom of Union?
-
Two sets can be paired to form a new set.
-
A set can be defined by its properties.
-
The union of two sets is the set of all elements that are in either set.
-
Every set has a unique complement.
The Axiom of Union states that the union of two sets A and B is the set of all elements that are in either A or B. This means that the union of two sets is the smallest set that contains all the elements of both sets.
What is the Axiom of Choice?
-
Two sets can be paired to form a new set.
-
A set can be defined by its properties.
-
The union of two sets is the set of all elements that are in either set.
-
Given a collection of non-empty sets, there exists a function that selects an element from each set.
The Axiom of Choice states that given a collection of non-empty sets, there exists a function that selects an element from each set. This means that it is always possible to make a choice from a collection of sets, even if the collection is infinite.
What is Russell's Paradox?
-
A set that contains itself as an element.
-
A set that is empty.
-
A set that is infinite.
-
A set that is well-ordered.
Russell's Paradox is a contradiction that arises from the idea of a set that contains itself as an element. This paradox led to the development of Axiomatic Set Theory, which is designed to avoid such contradictions.
What is the Zermelo-Fraenkel set theory?
-
A set of axioms used to define the concept of a set.
-
A set of axioms used to define the concept of a function.
-
A set of axioms used to define the concept of a relation.
-
A set of axioms used to define the concept of a number.
The Zermelo-Fraenkel set theory is a set of axioms used to define the concept of a set. It is the most widely accepted foundation for modern mathematics.
Which of the following is not an axiom of Zermelo-Fraenkel set theory?
-
The Axiom of Extensionality
-
The Axiom of Pairing
-
The Axiom of Union
-
The Axiom of Infinity
The Axiom of Infinity is not an axiom of Zermelo-Fraenkel set theory. It is an additional axiom that can be added to the theory to allow for the existence of infinite sets.
What is the Axiom of Regularity?
-
Every non-empty set contains an element that is disjoint from the set.
-
Every non-empty set contains an element that is a subset of the set.
-
Every non-empty set contains an element that is a proper subset of the set.
-
Every non-empty set contains an element that is a member of the set.
The Axiom of Regularity states that every non-empty set contains an element that is disjoint from the set. This means that there is no set that contains itself as an element.
What is the Axiom of Replacement?
-
If a set A is a subset of a set B, then there exists a set C that is isomorphic to A and a function f from B to C such that f(A) = C.
-
If a set A is a subset of a set B, then there exists a set C that is isomorphic to A and a function f from C to B such that f(A) = C.
-
If a set A is a subset of a set B, then there exists a set C that is isomorphic to A and a function f from A to C such that f(A) = C.
-
If a set A is a subset of a set B, then there exists a set C that is isomorphic to A and a function f from B to A such that f(A) = C.
The Axiom of Replacement states that if a set A is a subset of a set B, then there exists a set C that is isomorphic to A and a function f from B to C such that f(A) = C. This means that if we have a set A and a property P, then we can replace all the elements of A that satisfy P with a new element that also satisfies P, and the resulting set will be isomorphic to A.
What is the Power Set Axiom?
-
For any set A, there exists a set B that contains all the subsets of A.
-
For any set A, there exists a set B that contains all the elements of A.
-
For any set A, there exists a set B that is isomorphic to A.
-
For any set A, there exists a set B that is a proper subset of A.
The Power Set Axiom states that for any set A, there exists a set B that contains all the subsets of A. This means that for any set A, we can create a new set that contains all the sets that can be formed by taking different combinations of the elements of A.
What is the Axiom of Choice?
-
Given a collection of non-empty sets, there exists a function that selects an element from each set.
-
Given a collection of non-empty sets, there exists a set that contains all the elements of all the sets in the collection.
-
Given a collection of non-empty sets, there exists a set that is isomorphic to the union of all the sets in the collection.
-
Given a collection of non-empty sets, there exists a set that is a proper subset of the union of all the sets in the collection.
The Axiom of Choice states that given a collection of non-empty sets, there exists a function that selects an element from each set. This means that it is always possible to make a choice from a collection of sets, even if the collection is infinite.
What is the Axiom of Infinity?
-
There exists a set that contains infinitely many elements.
-
There exists a set that is isomorphic to the set of natural numbers.
-
There exists a set that is a proper subset of the set of natural numbers.
-
There exists a set that is a superset of the set of natural numbers.
The Axiom of Infinity states that there exists a set that contains infinitely many elements. This means that there is a set that cannot be put into one-to-one correspondence with the set of natural numbers.
What is the Axiom of Foundation?
-
Every non-empty set contains a minimal element.
-
Every non-empty set contains a maximal element.
-
Every non-empty set contains an element that is disjoint from the set.
-
Every non-empty set contains an element that is a member of the set.
The Axiom of Foundation states that every non-empty set contains a minimal element. This means that there is a set that does not contain any proper subsets.
