Stability of Radial Basis Function Methods for Convection Problems on the Circle and Sphere

It is proved that the RBF method is Lax-stable for problems on the circle when the collocation points are equispaced and the transport speed is constant, and it is proposed that the least-squares method can substantially improve stability without any increase to computational cost and with only a minor cost to accuracy.
