Several examples are discussed, some of them in relationship with the usual theory of regular space curves. The case of Lorentz–Minkowski sphere . is sketched only from the point of view of the geodesic curvature.

,Solitons in ,-Gravity,ent Yamabe solitons, .-Ricci and gradient .-Ricci solitons are its metrics. We establish criteria for which Ricci solitons are steady, expanding, or shrinking. Moreover, we study gradient Ricci solitons and prove that either the perfect fluid spacetime represents the dark energy era, or the spacetim

Pythagorean Submanifolds,odels of real space forms. They are defined by an equation based on the shape operator. We give several examples and observe that any Pythagorean submanifold is isoparametric where the principal curvatures are given in terms of the Golden ratio. We also classify Pythagorean hypersurfaces.
