I₂-convergence and I₂-cauchy double sequences in topological groups
(Zonguldak Bülent Ecevit Üniversitesi, 2018-05)
Let 2N×N be a family of all subsets of N×N. Following the definition of ideal convergence in a metric space by Kostyrko et al. in 2000, ideal convergence for double sequences in a metric space was introduced by Das et al. ...
Isometric deformation of (m, n)-type helicoidal surface in the three dimensional euclidean space
(2018)
We consider a new kind of helicoidal surface for natural numbers (m, n) in the three-dimensional Euclidean space. We study a helicoidal surface of value (m, n), which is locally isometric to a rotational surface of value ...
Rough I2-lacunary statistical convergence of double sequences
(Springer, 2018-08)
In this paper, we introduce and study the notion of rough I2-lacunary statistical
convergence of double sequences in normed linear spaces. We also introduce the
notion of rough I2-lacunary statistical limit set of a ...
The gauss map and the third laplace-beltrami operator of the rotational hypersurface in 4-space
(2018)
We study and examine the rotational hypersurface and its Gauss map in Euclidean four-space E4 . We calculate the Gauss map, the mean curvature and the Gaussian curvature of the rotational hypersurface and obtain some ...
