Ruled surfaces constructed by quaternions

S Aslan, M Bekar, Y Yaylı - Journal of Geometry and Physics, 2021 - Elsevier
In this paper, we define a quaternionic operator whose scalar part is a real parameter and
vector part is a curve in three dimensional real vector space R 3. We prove that quaternion …

Along with other types of calculus, multiplicative calculus brings an entirely new perspective.
Geometry now has a new field as a result of this new understanding. In this study …

SPLIT QUATERNIONS and CANAL SURFACES in MINKOWSKI 3-SPACE.

S ASLAN, Y YAYLI - International Journal of Geometry, 2016 - search.ebscohost.com
A canal surface is the envelope of a one-parameter set of spheres in three-dimensional
spaces. In this study, we have defined two canal surfaces by using unit timelike split …

Quaternionic approach of canal surfaces constructed by some new ideas

İ Gök - Advances in Applied Clifford Algebras, 2017 - Springer
A canal surface is a surface constructed as the envelope of a family of spheres with the
parametric (non constant radii) radii r (s) and a space curve α (s) α (s) called its center. If the …
