We investigate the singular limit, as, of the Allen-Cahn equation, withfa balanced bistable nonlinearity. We consider rather general initial datau0that is independent of. It is known that this equation converges to the generalized motion by mean curvature — in the sense of viscosity solutions—defined by Evans, Spruck and Chen, Giga, Goto. However, the convergence rate has not been known. We prove that the transition layers of the solutionsare sandwiched between two sharp “interfaces” moving by mean curvature, provided that these “interfaces” sandwich att= 0 anneighborhood of the initial layer. In some special cases, which allow bothextinctionandpinches offphenomenon, this enables to obtain anestimate of the location and thethickness measured in space-timeof the transition layers. A result on theregularity of the generalized motion by mean curvatureis also provided in the Appendix.
