Original · EN
We describe some connections, via composition, between two functional spaces: the space of (sub)critical branching mechanisms and the space of Bernstein functions. The functions eα: x→ xα where x≥0 and 0<α≤ 1/2, and in particular the critical parameter α=1/2, play a distinguished role.
