We start by introducing and studying two sequences of curvatures provided by the higher-
order derivatives of the usual Frenet equation of a given plane curve C. These curvatures …

In this paper, first, we defined normal Fermi-Walker derivative and applied for adapted
frame. Normal Fermi-Walker parallelism, normal non-rotating frame and Darboux vector of …

We introduce and study a Darboux mate of a given spherical Legendre curve LC for the
Euclidean S 2. Also, a triple sequence of curvatures is provided by the higher order …

We introduce and study a deformation of the geodesic curvature for a given spherical curve
γ. Also, wedefine a new type of evolute and two Fermi-Walker type derivatives for γ. Some …

We introduce and study a new curvature function for plane curves inspired by the weighted
mean curvature of M. Gromov. We call it rotational being the difference between the usual …

We introduce and study a new curvature function for plane curves inspired by the weighted
mean curvature of M. Gromov. We call it Pólya, being the difference between the usual …

In this paper, fantastic (weak) hyper filters in hyper BE-algebras are introduced and
investigated. The relationships between fantastic (weak) hyper filters and (weak) hyper filters …

We introduce and study a new curvature function for plane curves inspired by the weighted
mean curvature of M. Gromov. We call it radial being the difference between the usual …

We introduce and study a new frame and a new curvature function for a fixed
parametrization of a plane curve. This new frame is called flow since it involves the time …
