In this paper we define nnth order Hessian structures on manifolds and study them. In particular, when n=3n = 3, we make a detailed study and establish a one-to-one correspondence between {\it third-order Hessian structures} and a {\it certain class of connections} on the second-order tangent bundle of a manifold. Furt…

Higher-order tangent bundles have geometric structures compatible with their iterated bundle structure.

problem Connection towers and Sasaki metrics on higher-order tangent bundles
method Introduce the notion of a connection tower and study the geometric structures induced by such towers.
result Connection towers determine multiconnections, adapted splittings, and canonical vector bundle structures.

We compare two ways of interpreting higher order connections. The geometric approach lies in the decomposition of higher order tangent space into the horizontal and vertical structures while the jet--like approach considers a higher order connection as the section of a jet prolongation of a fibered manifold. Particular…

We introduce a notion of natural orderings of elements of finite connected quandles of order nn. When the elements of such a quandle QQ are already ordered naturally, any automophism on QQ is a natural ordering. Although there are many natural orderings, the operation tables for such orderings coincide when the perm…

Flat surfaces that correspond to kk-differentials on compact Riemann surfaces are of finite area provided there is no pole of order kk or higher. We denote by \textit{flat surfaces with poles of higher order} those surfaces with flat structures defined by a kk-differential with at least one pole of order at least $k…

General Relativity in 4 dimensions can be equivalently described as a dynamical theory of SO(3)-connections rather than metrics.
