The containment problem for symbolic and ordinary powers of ideals asks for what values ofaandbwe have. Over a regular ring, a result by Ein–Lazarsfeld–Smith, Hochster–Huneke, and Ma–Schwede partially answers this question, but the containments it provides are not always best possible. In particular, a tighter containment conjectured by Harbourne has been shown to hold for interesting classes of ideals—although it does not hold in general. In this paper, we develop a Fedder (respectively, Glassbrenner) type criterion forF-purity (respectively, strongF-regularity) for ideals of finite projective dimension overF-finite Gorenstein rings and use our criteria to extend the prime characteristic results of Grifo–Huneke to singular ambient rings. For ideals of infinite projective dimension, we prove that a variation of the containment still holds, in the spirit of work by Hochster–Huneke and Takagi.
