We explore adiabatic and nonadiabatic superconducting phases in monolayer blue phosphorene using first-principle calculations for both the hole and electron doping systems. We show the topology of the hole-doped Fermi surface is significantly vital for the transport properties of doped blue phosphorene. The combination of the temperature dependence of the bare susceptibility and the strong electron-phonon interaction gives rise to a charge density wave below the Lifshitz transition point. Having included nonadiabatic effects, we could analyze conditions for which either a superconductive or charge density wave phase occurs in the system. For quite low hole-doped of the system, a strong electron-phonon coupling leads to a nonadiabatic superconductive critical temperature of 96 K in the system.
