Poincaré series of the multigraded algebras of SL 2-invariants

  • Published:
Ukrainian Mathematical Journal Aims and scope

We deduce formulas for finding the Poincaré multiseries \( \mathcal{P}\left( {{\mathcal{C}_d},{z_1},{z_2}, \ldots, {z_n},t} \right) \) and \( \mathcal{P}\left( {{\mathcal{I}_d},{z_1},{z_2}, \ldots, {z_n}} \right) \), where \( {\mathcal{C}_d} \) and \( {\mathcal{I}_d} \), d = (d 1, d 2, . . . , d n ), are multigraded algebras of joint covariants and joint invariants for n binary forms of degrees d 1, d 2, . . . , d n .
