We study the electronic instabilities of doped bilayer silicene using the random phase approximation. In contrast to the singlet $d+i{d}^{\ensuremath{'}}$ superconductivity at the low doping region, we find that the system is an itinerant ferromagnet in the narrow doping regions around the Van Hove singularities, and a triplet $p+i{p}^{\ensuremath{'}}$ superconductor …
