The classical coinvariant ringis defined as the quotient of a polynomial ring innvariables by the positive-degree-invariants. It has a known basis that respects the decomposition ofinto irreducible-modules, consisting of thehigher Specht polynomialsdue to Ariki, Terasoma, and Yamada (Hiroshima Math J 27(1):177–188, 1997). We provide an extension of the higher Specht basis to the generalized coinvariant ringsintroduced in Haglund et al. (Adv Math 329:851–915, 2018). We also give a conjectured higher Specht basis for the Garsia–Procesi modules, and we provide a proof of the conjecture in the case of two-row partition shapes. We then combine these results to give a higher Specht basis for an infinite subfamily of the modulesrecently defined by Griffin (Trans Amer Math Soc, to appear, 2020), which are a common generalization ofand.
