Special Bertrand Curves in semi-Euclidean space E4^2 and their Characterizations
In [14] Matsuda and Yorozu.explained that there is no special Bertrand curves in Eⁿ and they new kind of Bertrand curves called (1,3)-type Bertrand curves Euclidean space. In this paper , by using the similar methods given by Matsuda and Yorozu [14], we obtain that bitorsion of the quaternionic curve is not equal to zero in semi-Euclidean space E4^2. Obtain (N,B2) type quaternionic Bertrand cur...
متن کاملCubic Ruled Surfaces with Constant Distribution Parameter in E4
A first order invariant of ruled surfaces of E3 is the socalled distribution parameter d in a generator. It is defined as the limit of the quotient of the distance and the angle of the generator and its neighbour. Ruled surfaces with constant parameter of distribution are of special interest and have been studied by many authors. H. Brauner could prove that the only nontrivial cubic ruled surfa...
متن کاملSingularities of Parallel Surfaces
We investigate singularities of all parallel surfaces to a given regular surface. In generic context, the types of singularities of parallel surfaces are cuspidal edge, swallowtail, cuspidal lips, cuspidal beaks, cuspidal butterfly and 3-dimensional D4 singularities. We give criteria for these singularities types in terms of differential geometry (Theorem 3.4 and 3.5).
متن کاملParallel Semi-Implicit Time Integrators
In this paper, we further develop a family of parallel time integrators known as Revisionist Integral Deferred Correction methods (RIDC) to allow for the semiimplicit solution of time dependent PDEs. Additionally, we show that our semi-implicit RIDC algorithm can harness the computational potential of multiple general purpose graphical processing units (GPUs) in a single node by utilizing exist...
متن کاملMeridian Essence: Modern Thought
Meridian essence has been investigated through anatomy, electrophysiology, biophysics, and biochemistry. Various hypotheses of meridian essence exist, but no hypothesis can truly reflect the internal character of Chinese medicine (CM). The research of meridian essence requires a holistic viewpoint and innovative awareness. Initially, any hypothesis regarding meridian essence should begin with o...
