Lines of Principal Curvature on Canal Surfaces in R3

In this paper are determined the principal curvatures and principal curvature lines on canal surfaceswhich are the envelopes of families of spheres with variable radius and centers moving along aclosed regular curve in R3. By means of a connection of the differential equations for thesecurvature lin...
