New Viewpoints in the Geometry of Submanifolds of R
0. Introduction. The geometry of submanifolds of euclidean space is the oldest branch of differential geometry. The subject was the original source of most of the classical and modern ideas in the field, and still is the setting in which seemingly complicated general phenomena are most easily understood. In fact as Allendoerfer [1] once said " . . . an excellent way of discovering [theorems] is...
متن کاملRecurrent metrics in the geometry of second order differential equations
Given a pair (semispray $S$, metric $g$) on a tangent bundle, the family of nonlinear connections $N$ such that $g$ is recurrent with respect to $(S, N)$ with a fixed recurrent factor is determined by using the Obata tensors. In particular, we obtain a characterization for a pair $(N, g)$ to be recurrent as well as for the triple $(S, stackrel{c}{N}, g)$ where $stackrel{c}{N}$ is the canonical ...
متن کاملSome problems in differential geometry and topology
The general setting here is that one would like to understand the classification of manifolds, and related objects such as knots in 3-space. The “classification”means up to an appropriate equivalence, and for definiteness we will consider smooth (i.e. differentiable) manifolds up to diffeomorphism (equivalence by differentiable homeomorphisms). Of course, what one really seeks is an understandi...
