Abstract
In TohÇneanu (2005), TohÇneanu introduced a triangulation ÎT with the following property: the space of splines of smoothness r
and degree 2r defined on ÎT has a dimension not equal to the lower bound found by Schumaker in Schumaker (1979). In MinÃ Ä and TohÇneanu (2013), it was shown that for dâ¥2r+1, the dimension of the space of splines on ÎT is equal to the lower bound. We show that this phenomenon can be explained by intrinsic supersmoothness of splines. Moreover, using this supersmoothness we obtain the dimension of the space of splines of smoothness r
and degree â¤2r on ÎT.
