Random Diophantine equations in the primes

open access: yesMathematika, Volume 72, Issue 3, July 2026.
Abstract We consider equations of the form a1x1k+⋯+asxsk=0$a_{1}x_{1}^{k}+\cdots +a_{s}x_{s}^{k}=0$ where the variables xi$x_{i}$ are all taken to be primes. We define an analogue of the Hasse principle for solubility in the primes (which we call the prime Hasse principle), and prove that, whenever k⩾2$k\geqslant 2$, s⩾3k+2$s\geqslant 3k+2$, this holds

On the infinite divisibility of the ratio of two gamma-distributed variables

open access: yes, 1978
It is shown that the distribution of the ratio of two independent gamma-distributed random variables is infinitely divisible. This result provides a solution to an unsolved problem given by F. W.

Quantitative asymptotics for polynomial patterns in the primes

open access: yesMathematika, Volume 72, Issue 3, July 2026.
Abstract We prove quantitative estimates for averages of the von Mangoldt and Möbius functions along polynomial progressions n+P1(m),…,n+Pk(m)$n+P_1(m),\ldots, n+P_k(m)$ for a large class of polynomials Pi$P_i$. The error terms obtained save an arbitrary power of logarithm, matching the classical Siegel–Walfisz error term.

Some recent results in infinite divisibility

open access: yes
In this paper, a survey is given of some recent developments in infinite divisibility. There are three main topics: (i) the occurrence of infinitely divisible distributions in applied stochastic processes such as queueing processes and birth-death ...

Some new results of infinite divisibility on the half-line

open access: yes, 2015
Cette thèse donne de nouveaux résultats de lois infiniment divisibles. La résolution d'une conjecture de Steutel (1973) à propos de la divisibilité infinie des puissances d'une variable gamma, et d'une conjecture de Bondesson (1992) à propos de la ...

Aspects of Randomization in Infinitely Divisible and Max-Infinitely Divisible Laws

open access: yes, 2003
Continuing the study reported in Satheesh (2001),(arXiv:math.PR/0304499 dated 01May2003) here we study certain aspects of randomization in infinitely divisible (ID) and max-infinitely divisible (MID) laws. They generalize ID and MID laws. In particular we study mixtures of ID & MID laws, its relation to random sums & random maximums ...

Infinite divisibility of random variables and their integer parts

open access: yes
It is examined to what extent the infinite divisibility of a random variable X entails the infinite divisibility of its integer part [X] or vice versa.

Infinite divisibility of sub-stable processes. Part I. geometry of sub-spaces of Lα-space

open access: yes, 1995
Generalizing the definition of sub-Gaussian processes we define a sub-stable process as a scale mixture of symmetric stable processes and study its infinite divisibility.
