• CURVES ON RULED SURFACES UNDER INFINITESIMAL BENDING 

      Najdanović, Marija; Maksimović, Miroslav; Velimirović, Ljubica (Faculty of Sciences and Mathematics, University of Priština in Kosovska Mitrovica, Republic of Serbia., 2021-01-01)
      Infinitesimal bending of curves lying with a given precision on ruled surfaces in 3-dimensional Euclidean space is studied. In particular, the bending of curves on the cylinder, the hyperbolic paraboloid and the helicoid ...
    • Infinitesimal bending of knots and energy change 

      Kauffman, Louis; Velimirović, Ljubica; Najdanović, Marija; Rančić, Svetozar (World Scientific Publishing Co. Pte. Ltd., 2019-09-12)
      We discuss the infinitesimal bending of curves and knots in R3. A brief overview of the results on the infinitesimal bending of curves is outlined. Change of the Willmore energy, as well as of the Möbius energy under ...
