arXiv:2611.13290v1 Announce Type: new Abstract: The focus of this manuscript is existence criteria for bounded point evaluations and bounded point derivations. In the single variable setting conditions for the existence of bounded point evaluations and derivations are known for many spaces of functions; however, in the several variable case far less is known. In this manuscript, we consider Campanato spaces, which contain many other function spaces as special cases, and prove sufficient conditions for the existence of bounded point evaluations in these spaces that are analogs of known results for the single variable case. We also demonstrate that for certain cases these sufficient conditions are also necessary.
