Also, in the present study, we consider weak biharmonic and harmonic 1-type curves by using the mean curvature vector field of the curve. We also study 1-type and biharmonic curves whose mean curvature vector field is in the kernel of Laplacian. We give some theorems for such curves in the Euclidean 3-space. Moreover, we give the classifications of these types of curves. © MatDer.eninfo:eu-repo/semantics/openAccessAlternative framebiharmonic curvesharmonic curvesArticle15111812410.47000/tjmcs.11410252-s2.0-85202536213N/A1184105
