Divergence-free colliding thoughts

Have you ever read a subject of interest that was barely relevant to what you were doing right then and found out it was the solution of somebody else's problem. This just happened to me this week-end. I received the NA Digest newletters with a question on divergence free and interpolating functions. Well it just so happens that I found recently an excellent resource on campus here at Texas A&M University. They have begun digitizing all the M.S and Ph.D theses produced by this fine institution, they are available at: https://txspace.tamu.edu/.In this database, I found the doctoral thesis of Svenja Lowitzsch on Approximation and interpolation employing divergence-free radial basis functions with applications.
