• Algebraic surfaces of the laplace-beltrami operators of the TF-type surfaces 

      Güler, Erhan; Yaylı, Yusuf; Hacısalihoğlu, Hasan Hilmi; Saraçoğlu Çelik, Semra (Yıldız Teknik Üniversitesi, 2015)
      We study on a new kind of surface covered by translation and factorable (TF-type) surfaces in the three dimensional Euclidean space. We calculate I and III Laplace-Beltrami operator surfaces of a TF-type ...

    • Enneper-type surfaces in three dimensional Minkowski space 

      Güler, Erhan; Saraçoğlu Çelik, Semra; Kişi, Ömer (International Conference on Recent Advances in Pure and Applied Mathematics, 2016)
      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.

    • New sequence spaces with respect to a sequence of modulus functions 

      Kişi, Ömer; Saraçoğlu Çelik, Semra; Güler, Erhan (3rd International Intuitionistic Fuzzy Sets and Contemporary Mathematics Conference (IFSCOM 2016), 2016-08-29)
      In this talk, we introduce the notion of AI-invariant statistical convergence, AI-lacunary invariant statistical convergence with respect to a sequence of modulus functions. We establish some inclusion relations between ...
    • Polynomial zero mean curvature surfaces in minkowski 3-space 

      Güler, Erhan; Saraçoğlu Çelik, Semra (Yıldız Teknik Üniversitesi, 2015)
      We consider the family of the polynomial zero mean curvature surfaces in three dimensional Euclidean and Minkowski spaces and compute their classes, degrees and integral free representations.
    • TF-type hypersurfaces in 4-Space 

      Güler, Erhan; Kişi, Ömer; Saraçoğlu Çelik, Semra (Mersin Üniversitesi, 2016)
      We study on translation and factorable hypersurfaces in the four dimensional Euclidean space. We calculate implicit algebraic equations of the hypersurfaces.
