In the present paper, we deal with the spherical indicatrices of involutes of a given spacelike curve with spacelike binormal. Then we give some important relationships between arc lengths and geodesic curvatures of the base curve and its involutes in Min... see more

In this paper, we study S-tangent surfaces according to Sabban frame in the Lorentzian Heisenberg group Heis³. We obtain differential equations about in terms of their geodesic curvatures in the Lorentzian Heisenberg group Heis³. Finally, we find explicit... see more

We analyzed null magnetic trajectories of a magnetic field on a timelike surface in Minkowski 3-space. We show that the Lorentz force can be written into the Darboux frame field of a null trajectory on the surface. We give the necessary and sufficient con... see more

In this paper we study the geometry of space and applications of this space to general theory of relativity. In space we obtained analog Ricci - Jacobi identity; the geodesic lines equation have been researched; we introduced analog of Darboux theory... see more

The length of the gravitational field lines/of the orthogonal trajectories of a family of gravity equipotential surfaces/of the plumbline between a terrestrial topographic point and a point on a reference equipotential surface like the geoid í also known ... see more

Internal flows in pipes are studied in greater depth and comprehensiveness in research. The computation done by using RANS equation. In particular, this study uses two equations turbulence model which is k-ε turbulence model. Mesh with 2×106 element is ... see more

This note is an effort to understand how curvature obstructs the integrability of almost-complex structures.

The exactness in determining the radius of curvature of the downstream toe of a spillway ensures a smooth hydraulic transit from the upstream to the downstream of the structure. The literature mentions that this radius takes half the height of the dam if ... see more

In this paper we have proved some results on conharmonically flat, quasi conharmonically flat and f-conharmonically flat LP-Sasakian manifolds with respect to Zamkovoy connection. Also, we study generalized conharmonic f-recurrent LP-Sasakian manifolds wi... see more
