We consider a 3-dimensional Riemannian manifold with an additional circulant structure, whose third power is the identity. This structure is compatible with the metric such that an isometry is induced in any tangent space of the manifold.

Geodesic Mappings Onto Riemannian Manifolds and Differentiability
, 2017In this paper we study fundamental equations of geodesic mappings of manifolds with affine connection onto (pseudo-) Riemannian manifolds. We proved that if a manifold with affine (or projective) connection of differentiability class C (r ≥ 2) admits a ...

Linear Weingarten rotational surfaces in pseudo-Galilean 3-space
, 2015In the present paper, we study rotational surfaces in the three dimensional pseudo-Galilean space G3. Also, we classify linear Weingarten rotational surfaces in G3.

In this study, we have generalized the involute and evolute curves of the spacelike curve α with a spacelike binormal in Minkowski 3- Space. Firstly, we have shown that, the length between the spacelike curve α and the timelike curve β is constant ...

On a motion of a line along two closed ruled surfaces
, 2015In this study, a closed motion given in R3 are considered in the dual space D3. Thus this motion is generalized to the D3. During this motion, some relations among the dual integral invariants of the closed ruled surfaces are given.

Almost Kähler Eight-Dimensional Walker Manifold
, 2018A Walker n-manifold is a pseudo-Riemannian manifold which admits a field of parallel null r-planes, with r ≤ n 2 . The canonical forms of the metrics were investigated by A. G. Walker [13]. Of special interest are the even-dimensional Walker manifolds (n

On nearly quasi-Einstein warped products
, 2016We study nearly quasi-Einstein warped product manifolds for arbitrary dimension n ≥ 3. In the last section we also give an example of warped product on nearly quasi-Einstein manifold. AMS Mathematics Subject Classification (2010): 53C25; 53B30; 53C15.

Spacelike maximal surface family prescribed by a spacelike curve in 3-dimensional Minkowski space
, 2016In this paper, we investigate spacelike maximal surface family prescribed by a given spacelike curve in Minkowski three space. We derive differential equation systems as necessary and sufficient condition for spacelike maximal surface family prescribed ...

Some characterizations of timelike canal surfaces according to Bishop frame in Minkowski 4-space
, 2016In this paper, we consider timelike canal surfaces according to Bishop frame in Minkowski 4-space E1. Thereafter, by using this, we investigated the curvature properties of these surfaces with respect to the principal curvature functions k1(s), k2(s), k3(

On the Gauss map of tubular surfaces in Galilean 3-space
, 2014In the present paper, we study tubular surfaces in Galilean 3-space G3. Also, we classify tubular surfaces in terms of an isometric immersion and the Gauss map of the surface.
