WebJan 1, 2024 · We give several new characterizations of completely monotone functions and Bernstein functions via two approaches: the first one is driven algebraically via elementary preserving mappings and the second one is developed in terms of the behavior of their restriction on N 0.We give a complete answer to the following question: Can we …
WebApr 3, 2007 · Such function are useful, for example, in probability theory. It is known, [1, p.450], for example, that a function w is the Laplace transform of an infinitely divisible probability distribution on (0,∞), if and only if w = e-h, where the derivative of h is completely monotonic and h(0+) = 0. WebFurthermore we have this characterization for completely monotone (CM) function : The following three assertions are equivalent: (a) ψ is completely monotone on ( 0, ∞) (respectively on [ 0, ∞) ); (b) ψ is represented as the Laplace transform of a unique Radon (respectively finite) measure ν on [ 0, ∞) : ψ ( λ) = ∫ [ 0, ∞) e − ...
