Streszczenie
We compute the moments and free cumulants of the measure $\rho_t:=\pi_t\mathbin{{\scriptstyle\boxtimes}}\pi_t$, where $\pi_t$ denotes the free Poisson law with parameter $t>0$. We also compute free cumulants of the symmetrization of $\rho_t$. Finally, we introduce the free symmetrization of a probability measure on $\mathbb{R}$ and provide some examples.
