Boost Invarıant Surfaces Wıth Poıntwıse 1-Type Gauss Map In Mınkowskı 4-Space E-1(4)
Aksoyak, Ferdag Kahraman; Yayli, Yusuf (KOREAN MATHEMATICAL SOC, 2014)In this paper, we study spacelike rotational surfaces which are called boost invariant surfaces in Minkowski 4-space E-1(4). We give necessary and sufficient condition for flat spacelike rotational surface to have pointwise ... -
CURVES OF CONSTANT BREADTH ACCORDING TO DARBOUX FRAME
Altunkaya, Bulent; Aksoyak, Ferdag Kahraman (ANKARA UNIV, FAC SCI, 2017)In this paper, we investigate constant breadth curves on a surface according to Darboux frame and give some characterizations of these curves. -
Flat Rotational Surfaces With Pointwıse 1-Type Gauss Map In E-4
Aksoyak, Ferdag Kahraman; Yayli, Yusuf (HONAM MATHEMATICAL SOC, 2016)In this paper we study general rotational surfaces in the 4-dimensional Euclidean space II and give a characterization of flat general rotational surface with pointwise 1-type Gauss map. Also, we show that a flat general ... -
GENERAL ROTATIONAL SURFACES WITH POINTWISE 1-TYPE GAUSS MAP IN PSEUDO-EUCLIDEAN SPACE E-2(4)
Aksoyak, Ferdag Kahraman; Yayli, Yusuf (INDIAN NAT SCI ACAD, 2015)In this paper, we study general rotational surfaces in the 4- dimensional pseudo-Euclidean space E-2(4) and obtain a characterization of flat general rotation surfaces with pointwise 1-type Gauss map in E-2(4) and give an ... -
Generalized Bicomplex Numbers and Lie Groups
Karakus, Siddika Ozkaldi; Aksoyak, Ferdag Kahraman (SPRINGER BASEL AG, 2015)In this paper, we define the generalized bicomplex numbers and give some algebraic properties of them. Also, we show that some hyperquadrics in and are Lie groups by using generalized bicomplex number product and obtain ... -
Homothetic Motions and Surfaces in E-4
Aksoyak, Ferdag Kahraman; Yayli, Yusuf (SPRINGER, 2015)In this paper, we determine a surface M by means of homothetic motion in R-4 and reparametrize this surface M with bicomplex numbers. Also, by using curves and surfaces which are obtained by homothetic motion, we give some ... -
A new type of quaternionic frame in R-4
Aksoyak, Ferdag Kahraman (WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)In this paper, we obtain a new version of Serret-Frenet formulae for quaternionic curve in R-4 by using a method similar to the method given by Bharathi and Nagaraj and called it Type 2-Quaternionic Frame. Also, we give ... -
Null Curves Of Constant Breadth In Mınkowskı 4-Space
Altunkaya, Bulent; Aksoyak, Ferdag Kahraman (ANKARA UNIV, FAC SCI, 2019)In this paper, we define null curves of constant breadth in Minkowski 4-space and obtain a characterization of these curves. Also we give an example for such curves.
