J-generalization of the Rogers–Ramanujan–Gordon identities via commutative algebra
摘要
The Rogers–Ramanujan–Gordon identities generalize the classical partition identities discovered independently by Rogers and Ramanujan. In 2021, Afsharijoo provided a commutative algebra proof of the Rogers–Ramanujan–Gordon identities. Building on the Afsharijoo’s approach, we present a commutative algebra proof of a broader family of identities introduced by Coulson et al., which includes the Rogers–Ramanujan–Gordon identities as a special case. In the proof, we relate the generating functions associated with these identities to the Hilbert–Poincaré series of suitably constructed graded algebras.
