AbstractIn the study of the curve shortening flow on general closed curves in the plane, Abresch and Langer posed a conjecture that the homothetic curves can be regarded as saddle points between multi-folded circles and certain singular curves. In other words, these homothetic curves are the watershed between curves with a nonsingular future and those with singular future along the flow. In this article, we provide an affirmative proof to this conjecture.
