리만기하학의 문제 Is a Riemannianmanifold (possibly with boundary) determined by its spectrum?
1964, John Milnor found two distinct 16-dimensional manifolds with the same spectrum.
1991년, CarolynGordon, David Webb, and Scott Wolpert found examples of distinct plane "drums"which "sound" the same. See the illustrations below.
