@inproceedings{IKrichever2006CharacterizingJV, title={Characterizing Jacobians via trisecants of the Kummer Variety}, author={I.Krichever}, year={2006} }
We prove Welter's trisecant conjecture: an indecomposable principally polarized abelian variety $X$ is the Jacobian of a curve if and only if there exists a trisecant of its Kummer variety $K(X)$.
