Quaternionic Product of Circles and Cycles and Octonionic Product for Pairs of Circles
This paper concerns with a product of circles induced by the quaternionic product considered in a projective manner. Several properties of this composition law are derived and on this way we arrive at some special numbers as roots or powers of unit. We extend this product to cycles as oriented circles and to pairs of circles by using the algebra of octonions. Three applications of the given pro...
متن کاملPlant Cytokinesis: Circles within Circles
The current model of the plant cytokinetic apparatus, describing it as being composed of treadmilling microtubules, is challenged by a new study showing that these microtubules display dynamic instability.
متن کاملIntroducing healing circles and talking circles into primary care.
We report on the incorporation of a North American aboriginal procedure called "the talking circle" into primary care in areas serving this population. Communication is regulated through the passing of a talking piece (an object of special meaning or symbolism to the circle facilitator, who is usually called the circle keeper). Twelve hundred people participated in talking circles in which 415 ...
متن کاملCurves, Circles, and Spheres
The standard radius of curvature at a point q(s) on a smooth curve can be defined as the limiting radius of circles through three points that all coalesce to q(s). In the study of ideal knot shapes it has recently proven useful to consider a global radius of curvature of the curve at q(s) defined as the smallest possible radius amongst all circles passing through this point and any two other po...
متن کاملSurfaces, circles, and solenoids
Previous work of the author has developed coordinates on bundles over the classical Teichmüller spaces of punctured surfaces and on the space of cosets of the Möbius group in the group of orientation-preserving homeomorphisms of the circle, and this work is surveyed here. Joint work with Dragomiř Sari´c is also sketched which extends these results to the setting of the Teichmüller space of the ...
