Zeta distributions generated by Dirichlet series and their (quasi) infinite divisibility

  title={Zeta distributions generated by Dirichlet series and their (quasi) infinite divisibility},
  author={Takashi Nakamura},
. Let a (1) > 0, a ( n ) ≥ 0 for n ≥ 2 and a ( n ) = O ( n ε ) for any ε > 0, and put Z ( σ + it ) := P ∞ n =1 a ( n ) n − σ − it where σ, t ∈ R . In the present paper, we show that any zeta distribution whose characteristic function is defined by Z σ ( t ) := Z ( σ + it ) /Z ( σ ) is pretended infinitely divisible if σ > 1 is sufficiently large. Moreover, we prove that if Z σ ( t ) is an infinitely divisible characteristic function for some σ id > 1, then Z σ ( t ) is infinitely divisible for all…

On Quasi-Infinitely Divisible Random Measures

In this work we show that a family of quasi-infinitely divisible (QID) completely random measures (CRMs) is dense in the space of all CRMs with respect to convergence in distribution. We prove the

On the extension and kernels of signed bimeasures and their role in stochastic integration

This work provides a necessary and sufficient condition for the extension of signed bimeasures on $\delta$-rings and for the existence of relative kernels and obtains the most general theory of stochastic integrals based on random measures.



The Riemann zeta distribution

Let æ be the Riemann zeta function. Khinchine (1938) proved that the function fó (t) ˆ æ(ó ‡ it)=æ(ó ), where ó . 1 and t is real, is an in®nitely divisible characteristic function. We investigate

On quasi-infinitely divisible distributions

A quasi-infinitely divisible distribution on $\mathbb{R}$ is a probability distribution whose characteristic function allows a Levy-Khintchine type representation with a "signed Levy measure", rather


Results on two topics on stochastic integrals with respect to Levy processes and infinitely divisible distributions are surveyed. The first topic is on the distributions of Poissonian exponential
