We construct an astrohelicoidal surface which its profile curve has astroid curve in the three dimensional Euclidean space E3. We also find Gaussian curvature and the mean curvature, and Weingarten relation of the surface ...

In this work, we study on anEnneper-typeminimal surfacesusing Weierstrass representation in the threedimensional Minkowskispace. We compute implicit equations, degree and class of the surfaces.

We define Ulisse Dini-type helicoidal hypersurfaces with spacelikeaxis in Minkowski 4-spaceE41. We compute the Gaussian and the mean curva-ture of the hypersurface. Moreover, we obtain some special symmetries to thecurvatures ...

In this talk, we extend the concepts of I-Limit superior and I-Limit inferior for reel number sequences to I-Limit superior and I-Limit inferior for sequences of sets, study their certain properties and establish some ...

In this study, we introduce the concept of lacunary I2-invariant convergence, lacunary I∗2-invariant convergence and lacunary I2-invariant Cauchy for double sequences in the topology introduced by random 2-normed spaces. ...

In this study, we introduce the notion of A^{I}-lacunary statistical convergence, strongly A^{I}-lacunary convergence with respect to a sequence of modulus functions. We study some collections between them. Also, we ...

We examine the fourth fundamental form of the translation hypersurface in the four dimensional Euclidean space. We also discuss I, II, III and IV fundamental forms of a translation hypersurface.
