Radially symmetric thin plate splines interpolating a circular contour map

摘要

Profiles of radially symmetric thin plate spline surfaces minimizing the Beppo Levi energy over a compact annulus R1≤r≤R2 have been studied by Rabut via reproducing kernel methods. Motivated by our recent construction of Beppo Levi polyspline surfaces, we focus here on minimizing the radial energy over the full semi-axis 0
