Pseudo-Riemannian VSI spaces II

Unlike the Black Sea region, where Russia has recently used—and continues to use—military force and other means of influence in a concerted effort to redraw

In Chapter 5, Norway’s role in previous international arms reduction processes is discussed, leading to an outline of a possible role for Norway as an NNWS in a future

The main difference between the sub-Riemannian manifold and Riemannian one is the presence of a smooth subbundle of the tangent bundle, generating the entire tangent bundle by means

In Riemannian geometry we can define a unique linear connection, called the Levi-Civita con- nection, which is not necessarily the case in sub-Riemannian geometry.. The uniqueness

For any compact Riemannian surface of positive genus, we will construct a flat P 1 bundle over it such that the total space is a projective manifold, and a Stein domain with

The energy preserving discrete gradient methods are generalized to finite-dimensional Riemannian manifolds by definition of a discrete approximation to the Riemannian gradient,

In section 3, we present the discrete Riemannian gradient (DRG) methods, a convergence proof for the family of optimization meth- ods obtained by applying DRG methods to
