Abstract: | In this paper we give a new definition of harmonic curvature functions in terms of B 2 and we define a new kind of slant helix which we call quaternionic B 2–slant helix in 4–dimensional Euclidean space E 4 by using the new harmonic curvature functions. Also we define a vector field D which we call Darboux quaternion of the real quaternionic B 2–slant helix in 4–dimensional Euclidean space E 4 and we give a new characterization such as: "a: I ì mathbb R ? E4{``alpha : I subset {mathbb R} rightarrow E^4} is a quaternionic B 2–slant helix ${Leftrightarrow H^prime_2 -KH_{1} = 0"}${Leftrightarrow H^prime_2 -KH_{1} = 0"} where H 2, H 1 are harmonic curvature functions and K is the principal curvature function of the curve α. |
