摘要: It is known that the Deligne-Mumford compactification MDMg,n of the moduli space Mg,n is a projective algebraic variety. In this paper, we construct a new space MDMg,n, homeomorphic to MDMg,n, by the projections of complex earthquakes for one weighted simple closed curve in Mg,n. Moreover, we give a formula of limit distance between complex earthquake and Teichmuller disk in moduli space.
