What is the Continuum Hypothesis?

  1. The hypothesis that the cardinality of the set of real numbers is equal to the cardinality of the set of integers.

  2. The hypothesis that the cardinality of the set of real numbers is greater than the cardinality of the set of integers.

  3. The hypothesis that the cardinality of the set of real numbers is less than the cardinality of the set of integers.

  4. The hypothesis that the cardinality of the set of real numbers is equal to the cardinality of the set of rational numbers.


Correct Option: A
Explanation:

The Continuum Hypothesis states that the cardinality of the set of real numbers, denoted by (\aleph_1), is equal to the cardinality of the set of integers, denoted by (\aleph_0).

What is the cardinality of the set of real numbers?

  1. $\aleph_0$

  2. $\aleph_1$

  3. $\aleph_2$

  4. $\aleph_3$


Correct Option: B
Explanation:

The cardinality of the set of real numbers is denoted by (\aleph_1), which represents the first uncountable cardinal number.

What is the cardinality of the set of integers?

  1. $\aleph_0$

  2. $\aleph_1$

  3. $\aleph_2$

  4. $\aleph_3$


Correct Option: A
Explanation:

The cardinality of the set of integers is denoted by (\aleph_0), which represents the smallest infinite cardinal number.

Is the Continuum Hypothesis true or false?

  1. True

  2. False

  3. Undecidable


Correct Option: C
Explanation:

The Continuum Hypothesis is currently undecidable within the framework of Zermelo-Fraenkel set theory, which is the standard foundation of modern mathematics.

What is the Generalized Continuum Hypothesis?

  1. The hypothesis that the cardinality of the set of real numbers is equal to the cardinality of the set of integers.

  2. The hypothesis that the cardinality of the set of real numbers is greater than the cardinality of the set of integers.

  3. The hypothesis that the cardinality of the set of real numbers is less than the cardinality of the set of integers.

  4. The hypothesis that the cardinality of the set of real numbers is equal to the cardinality of the set of rational numbers.


Correct Option: B
Explanation:

The Generalized Continuum Hypothesis states that the cardinality of the set of real numbers is greater than the cardinality of the set of integers, but less than the cardinality of the set of all sets.

What is the relationship between the Continuum Hypothesis and the Generalized Continuum Hypothesis?

  1. The Generalized Continuum Hypothesis implies the Continuum Hypothesis.

  2. The Continuum Hypothesis implies the Generalized Continuum Hypothesis.

  3. The two hypotheses are independent of each other.

  4. None of the above.


Correct Option: A
Explanation:

The Generalized Continuum Hypothesis implies the Continuum Hypothesis, but the converse is not true.

Which mathematician is credited with formulating the Continuum Hypothesis?

  1. Georg Cantor

  2. David Hilbert

  3. Kurt Gödel

  4. Paul Cohen


Correct Option: A
Explanation:

Georg Cantor, the founder of set theory, formulated the Continuum Hypothesis in 1878.

Which mathematician proved the independence of the Continuum Hypothesis from the axioms of Zermelo-Fraenkel set theory?

  1. Georg Cantor

  2. David Hilbert

  3. Kurt Gödel

  4. Paul Cohen


Correct Option: D
Explanation:

Paul Cohen proved the independence of the Continuum Hypothesis from the axioms of Zermelo-Fraenkel set theory in 1963.

What is the significance of Cohen's proof?

  1. It showed that the Continuum Hypothesis is true.

  2. It showed that the Continuum Hypothesis is false.

  3. It showed that the Continuum Hypothesis is independent of the axioms of Zermelo-Fraenkel set theory.

  4. None of the above.


Correct Option: C
Explanation:

Cohen's proof showed that the Continuum Hypothesis is independent of the axioms of Zermelo-Fraenkel set theory, meaning that it can neither be proven nor disproven within the framework of this theory.

What are some of the implications of Cohen's proof?

  1. The Continuum Hypothesis is true.

  2. The Continuum Hypothesis is false.

  3. The Continuum Hypothesis is independent of the axioms of Zermelo-Fraenkel set theory.

  4. The axioms of Zermelo-Fraenkel set theory are inconsistent.


Correct Option: C
Explanation:

Cohen's proof showed that the Continuum Hypothesis is independent of the axioms of Zermelo-Fraenkel set theory, meaning that it can neither be proven nor disproven within the framework of this theory.

What is the current status of the Continuum Hypothesis?

  1. It is true.

  2. It is false.

  3. It is independent of the axioms of Zermelo-Fraenkel set theory.

  4. None of the above.


Correct Option: C
Explanation:

The Continuum Hypothesis is currently undecidable within the framework of Zermelo-Fraenkel set theory, which is the standard foundation of modern mathematics.

What are some of the open questions related to the Continuum Hypothesis?

  1. Is the Continuum Hypothesis true or false?

  2. Can the Continuum Hypothesis be proven or disproven using a different set of axioms?

  3. Are there other mathematical theories in which the Continuum Hypothesis can be proven or disproven?
