A New Approach to the Invariants of the Ruled Surfaces with a Ruling Area Vector

open access: yes, 2010
In this paper, the area vector of a closed space curve and the Steineer vector of a motion are extensively studied by the methods of differential geometry. A new ruled surface whose ruling is the area vector of a closed space curve formed during a closed

Involutes of fronts in the Euclidean plane

open access: yes
application/pdfFor a regular plane curve, an involute of it is the trajectory described by the end of a stretched string unwinding from a point of the curve. Even for a regular curve, the involute always has a singularity.
