The fourth theorem states that, for a given fixed entropy, this flow is unique, up to a constant rescaling of time. The fifth theorem states that there is a single, unique flow (up to a constant rescaling of time) that has infinite entropy.
A crucial principle in this context states that for a fixed level of unpredictability, the system's behavior is uniquely defined, with time being adjusted proportionally. Another fundamental concept asserts that there is one specific process that embodies maximum uncertainty, also subject to time scaling adjustments.
