Decoupling the i.i.d. field and the randomisation field in the Curie-Weiss model
Yacine Barhoumi-Andréani, Peter Eichelsbacher
Using the De Finetti representation of the Curie-Weiss model, the uniform coupling of Bernoulli random variables and the Laplace inversion formula (almost surely), we show that the…
Splitting phenomenon in the Sathe-Selberg theorem, mod-Poisson convergence with auxiliary randomisation and universality of the Gamma factor
Yacine Barhoumi-Andréani
We consider several sequences of random variables whose Fourier-Laplace transforms present the same type of \textit{splitting phenomenon} when suitably rescaled by the Fourier-Lapl…
A surrogate by exchangeability approach to the Curie-Weiss model
Yacine Barhoumi-Andréani, Marius Butzek, Peter Eichelsbacher
We introduce a new general concept of surrogate random variable, the ``surrogate by exchangeability'' that allows to study the class of random variables that can be decomposed by m…
Remarkable structures in integrable probability, I: max-independence structures
Yacine Barhoumi-Andréani
We analyse in a systematic way the occurrences of a remarkable structure in the theory of integrable probability that we call a ``max-independence structure'', when random variable…
