Abstract: By J. F. Nash’s Theorem, any Riemannian manifold can be embedded into a Euclidean ambient space with dimension sufficiently large. S.-S. Chern pointed out in 1968 that a key technicality in applying Nash’s Theorem effectively is finding useful relationships between intrinsic and extrinsic elements which characterise immersions. After 1993, when a groundbreaking work written by B.-Y. Chen on this theme was published, many explorations pursued this avenue of inquiry. We describe new relationships involving intrinsic and extrinsic curvature invariants, under natural geometric conditions.
