Special canal surfaces with Bishop frame and quaternions [PDF]

open access: yesSurveys in Mathematics and its Applications
The purpose of this paper is to show that canal and tubular surfaces can be obtained by special curves. Also, we reckon the equations of these surfaces with Bishop frame and acquire some corollaries for special curves.

Canal surfaces in 4-dimensional Euclidean space

open access: yesAn International Journal of Optimization and Control: Theories & Applications (IJOCTA), 2016
In the present study, we consider canal surfaces imbedded in an Euclidean space of four dimensions. The curvature properties of these surface are investigated with respect to the variation of the normal vectors and curvature ellipse. We also give some special examples of canal surfaces in E^4.
