Sulla blalgebra duale della bialgebra dei polinomi in
più variabili
Abstract.
This paper is devoted to the study of the dual
bialgebra Bno of the
bialgebra Bn ofpolynomials in finitely many
variables. The elements of
Bno are described in various ways in order
to obtain some usefu!
formulae (e.g., a formula for the "remainder" modulo a cofinite ideal
of Bn). The subcoalgebra Cf
generated by a given
element f ∈ Bno is
studied and its structure constants with relation to different natural
bases are given.
