摘要The gravitational collapse of a massless scalar field enclosed with a perfectly reflecting wall in a spacetime with a cosmological constant Lambda is investigated. The mass scaling for the gapped collapse M-AH - M-g proportional to (epsilon(c)- epsilon)(xi) is confirmed and a new time scaling for the gapped collapse T-AH - T-g proportional to (epsilon(c)- epsilon)(xi) is found. For both the critical exponents, we find strong evidence to show that they are non-universal. Especially when A 0, we find that both of these two critical exponents depend on the combination Lambda R-2, where R is the radial position of the reflecting wall. We find an evolution of the critical exponent xi from 0.37 in the confined asymptotic dS case with Lambda R-2 = 1.75 to 0.68 in the confined asymptotic AdS case with Lambda R-2 =-1.75, while the critical exponent varies zeta from 0.10 to 0.26, which shows that the new critical behavior for the gapped collapse is essentially different from the Choptuik's case.
