We consider an astrohelicoidal hypersurface which its profile curve has astroid curve in the four dimensional Euclidean space E4. We also calculate Gaussian curvature and the mean curvature, and Weingarten relation of the ...

In this paper, we study the logaritmic spiral-type helicoidal surface in Euclidean 3-space. We obtain logaritmic spiral-type helicoidal surface with some figures, and calculate its curvatures.

We focus differential geometry of the Henry Smith surface in the three dimensional Euclidean space. We calculate the Gaussian and the mean curvatures of the surface, drawing its figure. In addition, we find algebraic ...

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 paper, we have investigated I2-λ-statistically convergence for double sequences in fuzzy normed linear spaces, where λ = (λr) and μ = (μs) be two non-decreasing sequences of positive real numbers, each tending to ...

We consider Ulisse Dini-type helicoidal hypersurfaces with timelike axis in Minkowski 4-space E41 . Calculating the Gaussian and the mean curvatures of the hypersurfaces, we demonstrate some special symmetries for the ...

We introduce double λ -statistically convergent sequences and double λ -statistically Cauchy sequences in the fuzzy normed spaces. We study [V,λ ] and [C,1]-summabilities for double sequences. In addition, we obtain the ...
