Low energy dynamics of a CP^1 lump on the sphere [PDF]

, 1995
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 ...

Variations of gwistor space [PDF]

, 2012
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.

g-Natural metrics on unit tangent sphere bundles via a Musso-Tricerri process [PDF]

Rendiconti di Matematica e delle Sue Applicazioni, 2010
E. Musso and F. Tricerri had given a process of construction of Riemannian metrics on tangent bundles and unit tangent bundles, over m-dimensional Riemannian manifolds (M, g), from some special quadratic forms an OM × R^m and OM, respectively, where OM ...

New Standards for Measurement in Meridians & Acupoints by Taking the Size of Normal Male Legs

Journal of Pharmacopuncture, 2010
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 ...

Kaleidoscopical graphs and semigroups [PDF]

Математичні Студії, 2011
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.

Completeness results for metrized rings and lattices [PDF]

Categories and General Algebraic Structures with Applications, 2019
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

$H$-contact unit tangent sphere bundles of Riemannian manifolds

, 2016
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 ...
