  We study homomorphisms on the algebra of analytic functions of bounded type
on a Banach space. When the domain space lacks symmetric regularity, we show
that in every fiber of the spectrum there are evaluations (in higher duals)
which do not coincide with evaluations in the second dual. We also consider the
commutativity of convolutions between evaluations. We show that in some Banach
spaces $X$ (for example, $X=\ell_1$) the only evaluations that commute with
every other evaluation in $X''$ are those in $X$. Finally, we establish
conditions ensuring the symmetry of the canonical extension of a symmetric
multilinear operator (on a non-symmetrically regular space) and present some
applications.
