Summary:
In this paper, we construct-and-study free (weighted-)Poisson
elements in the Banach *-probability space (LS, τ
0), generated by mutually free semicircular elements {Θ
{p,j}}{p ∈ P, j ∈ Z induced by measurable
functions on the p-adic number fields Q p, for all p
in the set P of all primes, and for all j in the set
Z of all integers. In~particular, we are interested in
free Poisson elements generated by certain free random
variables of (LS, τ 0) induced by semicircular elements.
