Axiomatic approach to the cosmological constant

Understand

A theory of the cosmological constant Lambda is currently out of reach.

• Still, one can start from a set of axioms that describe the most desirable properties a cosmological constant should have.
• This can be seen in certain analogy to the Khinchin axioms in information theory, which fix the most desirable properties an information measure should have and that ultimately lead to the Shannon entropy as the fundamental information measure on which statistical mechanics is based.
• Here we formulate a set of axioms for the cosmological constant in close analogy to the Khinchin axioms, formally replacing the dependency of the information measure on probabilities of events by a dependency of the cosmological constant on the fundamental constants of nature.
