III laplace beltrami and (S,L)-type rotational surface
(Longdom Publishing SL, 2012)We study on the third Laplace-Beltrami operator of timelike rotational surface of (S,L)-type in three dimensional Minkowski space. -
Implicit equations of the henneberg-type minimal surface in the four dimensional euclidean space
(2018)Considering the Weierstrass data as $(\psi ,f,g)=( 2,1-z^{-m},z^{n})$, we introduce a two parameter family of Henneberg type minimal surface that we call $\mathfrak{H}_{m,n}$ for positive integers $(m,n)$ by using the ... -
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 ... -
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. ... -

New convergence definitions for sequences of sets
(Abstract and Applied Analysis, 2013-09)Several notions of convergence for subsets of metric space appear in the literature. In this paper, we define Wijsman ---convergence and Wijsman --∗-convergence for sequences of sets and establish some basic theorems. ... -
A new kind of helicoidal surface of value m
(2014)We define a new kind of helicoidal surface of value m. A rotational surface which is isometric to the helicoidal surface of value m is revealed. In addition, we calculate some differential geometric properties of the ... -

On generalized euler spirals in E3
(2016)The Cornu spirals on plane are the curves whose curvatures are linear. Generalized planar cornu spirals and Euler spirals in E3, the curves whose curvatures are linear are deÖned in [1,5]. In this study, these curves are ... -
On I-asymptotically lacunary statistical equivalence of functions on amenable semigroups

On I_{σ}-convergence of folner sequence on amenable semigroups
(New Trends in Mathematical Sciences, 2018-04)In this paper, the concepts of-uniform density of subsetsAof the setof positive integers and corresponding-convergence of functions defined on discrete countable amenable semigroups were introduced. Furthermore, for any ... -
On statistical convergence with respect to measure
(Journal of Classical Analysis, 2017-01)Several notions of convergence for subsets of metric spaces appear in the literature. In this paper, for real valued measurable functions defined on a measurable space (X,M ,μ), we obtain a statistical version of Lebesque’s ... -

Quasi harmonic Bézier approximation of minimal surfaces for finding forms of structural membranes
(Elsevier, 2015)Numerical approximation of minimal surface is an important problem in form-finding of structural membranes. In this paper, we present a novel approach to construct minimal surface from a given boundary by quasi-harmonic ... -
Rotational hypersurfaces in S3(r)XR product space
(Sakarya University Journal of Science, 2017)We consider rotational hypersurfaces in S3(r)XR product space of five dimensional Euclidean space E^5. We calculate the mean curvature and the Gaussian curvature, and give some results.
