Abstract In this article, we study THA-surfaces in the Galilean space

In this paper, we introduce isophote curves on surfaces in Galilean 3-space. Apart from the general concept of isophotes, split our studies into two cases to get axis d lying a surface such that is an isotropic or non-isotropic vector. We also give method compute revolution. Subsequently, show relationship between and slant (general) helices revolution obtained by revolving curve Euclide...

in this paper mathematical structure of time-dependent lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent lagrangian systems are considered. starting point is time-independent lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to the...

Dynamical equations describing evolution of state functions in space-time of a given metric are important components of physical theories of particles. A method based on a group of the metric is used to obtain an infinite set of general dynamical equations for a scalar and analytical function representing free and spinless particles. It is shown that this set of equations is the same for any gr...

In this paper, we study the hypersurface families with Smarandache curves in 4-dimensional Galilean space G 4 and give conditions for different to be parameter curve which generates is geodesic on a . Also, investigate three types of marching-scale functions one these hypersurfaces construct an example it.
