Abstract
In order to find necessary conditions for a submanifold in a space form with codimension greater than one to admit isometric deformations, one has to take into account that any submanifold of a deformable submanifold already possesses the isometric deformations induced by the latter. Therefore, when studying the isometric deformations of a submanifold, one should look for the “genuine” ones, that is, those which are not induced by isometric deformations of an “extended” submanifold of higher dimension. Besides, it is also of interest to consider isometric deformations of a submanifold that take place in a possibly different codimension.
