摘　　要：We investigate the critical collapse of spherically symmetric scalar fields in asymptotically anti-de Sitter spacetime,focusing on two scenarios:real and complex scalar fields with potentials.By fine-tuning the amplitude of the initial scalar field under different cosmological constants,we find a linear relationship between the critical amplitude of the first collapse and the cosmological constant in both scenarios.Furthermore,we observe that the slope of this linear relationship varies linearly with coupling strength.
