Subalgebras of Free Associative AlgebrasProceedings of The London Mathematical Society
Let R be a commutative integral domain with unit, f be a nonconstant monic polynomial in R[t], and $$I_f \subset R[t]$$ I f ⊂ R [ t ] be the ideal generated by f. In this paper we study the group of R-algebra automorphisms of the R-algebra without unit $$I_f$$ I f . We show that, if f has only one root (possibly with multiplicity), then $${{\mathrm{Aut}}}(I_f) \cong R^\times $$ Aut ( I f ) ≅ R × . We also show that, under certain mild hypothesis, if f has at least two different roots in the algebraic closure of the quotient field of R, then $${{\mathrm{Aut}}}(I_f)$$ Aut ( I f ) is a cyclic group and its order can be completely determined by analyzing the roots of f.
