Priority and correctness on "From Schoenberg to Pick-Nevanlinna: Toward a complete picture of the variogram class" by Porcu and Schilling (2011, arXiv:0812.2936)
Abstract
It is not the purpose of this correspondence to complain about that six out of seven theorems listed in Porcu and Schilling (arXiv:0812.2936; 2011, Bernoulli) belong to others, but not to the authors themselves. This is simply a call for the priority, originality, and correctness.
