Annals of Mathematics 133(1): 217–247.0003-486Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:3597232We show cusps are dense in Bers' boundary for Teichmuller space. The proof rests on an estimate for the algebraic effect of a unit quasiconformal deformation supported in the thin part of the Riemann surface.en-USJournal Article2010-01-2810.2307/2944328
