Low energy dynamics of a CP^1 lump on the sphere [PDF]
Low-energy dynamics in the unit-charge sector of the CP^1 model on spherical space (space-time S^2 x R) is treated in the approximation of geodesic motion on the moduli space of static solutions, a six-dimensional manifold with non-trivial topology and ...

Hilbert Metric in the Unit Ball
The Hilbert metric between two points 𝑥, 𝑦 in a bounded convex domain 𝐺 is defined as the logarithm of the cross-ratio 𝑥, 𝑦 and the intersection points of the Euclidean line passing through the points 𝑥, 𝑦 and the boundary of the domain. Here, we study this metric in the case of the unit ball 𝔹𝑛.

Variations of gwistor space [PDF]
We study natural variations of the G2 structure {\sigma}_0 \in {\Lambda}^3_+ existing on the unit tangent sphere bundle SM of any oriented Riemannian 4-manifold M.

New Standards for Measurement in Meridians & Acupoints by Taking the Size of Normal Male Legs
Objective : Standard of measurement in Korean Medicine has been changed in dynasty and location. Thus, cun (寸) and chi (尺) as unit of measurement for meridians and acupoints could be recognized as the length of equally divided portions of a certain long ...

Completeness results for metrized rings and lattices [PDF]
The Boolean ring $B$ of measurable subsets of the unit interval, modulo sets of measure zero, has proper radical ideals (for example, $\{0\})$ that are closed under the natural metric, but has no prime ideal closed under that metric; hence closed radical

Kaleidoscopical graphs and semigroups [PDF]
We give a semigroup characterization of kaleidoscopical graphs. A connected graph Г (considered as a metric space with the path metric) is called kaleidoscopical if there is a vertex coloring of Г which is bijective on each unit ball.

Natural Paracontact Magnetic Trajectories on Unit Tangent Bundles
In this paper, we study natural paracontact magnetic trajectories in the unit tangent bundle, i.e., those that are associated to g-natural paracontact metric structures.

$H$-contact unit tangent sphere bundles of Riemannian manifolds
A contact metric manifold is said to be $H$-contact, if the characteristic vector field is harmonic. We prove that the unit tangent bundle of a Riemannian manifold $M$ equipped with the standard contact metric structure is $H$-contact if and only if $M ...
