Connections between the shape of the unit ball of a Banach space and a
nalytic properties of the Banach space have been studied for many year
s. Ln this article, some geometric properties of spaces related to n-h
omogeneous polynomials are considered. In particular, the rotundity an
d smoothness of spaces of continuous It-homogeneous polynomials and it
s preduals are studied. Furthermore, an inequality relating the produc
t of the norms of linear functionals on a Banach space with the norm o
f the continuous n-homogeneous polynomial determined by the product of
the linear functionals is derived. This inequality is used to study t
he strongly exposed points of the predual of the space of continuous 2
-homogeneous polynomials. (C) 1998 Academic Press.
