Rigidity for elliptic isometric imbeddings
Noboru Tanaka · Proceedings of the Japan Academy Series A Mathematical Sciences · 1972
Introduction.We say that an isometric imbedding f o a Riemannian manifold M to the Euclidean space R is elliptic if the imbedding f is generic in a suitable sense and if the differential operator L associated with f is elliptic.We then establish a rigidity
